A static analysis tool can be used by developers, testers and quality assurance personnel in looking for defects prior to dynamic testing, because it can analyse the code or design of the software under test without executing it and identify errors such as syntax errors, missing declarations, undefined variables, unused variables, or unreachable code . The other options are not tools that can be used by developers, testers and quality assurance personnel in looking for defects prior to dynamic testing. Option B is not a tool that can be used for this purpose, because a modeling tool is used to create graphical or textual representations of the software under test, such as state diagrams, data flow diagrams, or use cases . Option C is not a tool that can be used for this purpose, because a test data preparation tool is used to generate or manipulate data that are needed for executing the test cases or procedures . Option D is not a tool that can be used for this purpose, because a configuration management tool is used to manage and control the versions and changes of the software under test and the testware .

The correct answer is B, as it achieves the highest equivalence partition coverage. Equivalence partitioning is a black-box test technique that divides the input domain into partitions of equivalent data from which test cases can be derived1. In this case, the input domain is the numerical grades, and the partitions are the ranges of grades that correspond to different letter grades. Option B covers all five partitions, as it includes test inputs from each range. Option A covers only four partitions, as it does not include any test input from the range above 89. Option C covers only three partitions, as it does not include any test input from the ranges above 79 and below 60. Option D covers only two partitions, as it does not include any test input from the ranges below 79.

The correct answer is D, as it describes exploratory testing. Exploratory testing is an experience-based test technique that involves simultaneous learning, test design, and test execution1. Exploratory testing may be used within defined time periods, during which the tester may follow a test charter as a guide. A test charter is a document that specifies the scope, objective, and approach of an exploratory testing session1. Option A is incorrect, as exploratory testing is not a suitable test technique that may replace both black-box and white-box test techniques, but a complementary technique that can be used along with other techniques1. Option B is incorrect, as exploratory testing does not require both solid specifications and much project time available for test execution, but can be used in situations where specifications are incomplete or changing and where time is limited1. Option C is incorrect, as exploratory testing is not a valid and useful black-box test technique since it focuses on test cases related to the architecture and design of a system, but an experience-based test technique that focuses on learning about the system and its behavior1.

The statement that incidents cannot be raised during development is not true, because incidents can be raised during any stage of software development life cycle where deviations from expected or desired behaviour are observed . Incidents can be raised during development, review, testing or use of a software product . The other options are true statements about incidents.
