Option C is the correct way to initialize a jQuery widget in a JavaScript file. The widget name should be prefixed with “mage” and the options should be passed as an object literal. Option A is incorrect because it uses a dot notation instead of a colon to separate the widget name and the options. Option B is incorrect because it uses a string instead of an object literal to pass the options.

After compiling the .less file into a .css file, the result of the code above will be option B. This is because the .less file uses a mixin called .animation() that takes two parameters: the name of the animation and the duration. The mixin defines a set of vendor-prefixed properties for the animation and assigns them the values of the parameters. For example:

animation(@name; @duration) { -webkit-animation-name: @name; -webkit-animation-duration: @duration; -moz-animation-name: @name; -moz-animation-duration: @duration; animation-name: @name; animation-duration: @duration; }

When the mixin is called with the values “fade” and “2s”, it will generate the following CSS code:

-webkit-animation-name: fade; -webkit-animation-duration: 2s; -moz-animation-name: fade; -moz-animation-duration: 2s; animation-name: fade; animation-duration: 2s;

Option A is not correct because it does not use the vendor prefixes for the animation properties. Option C is not correct because it uses the wrong values for the animation name and duration. References: [LESS Mixins], [CSS Animations]

To delete a manually installed theme, the developer needs to remove the theme directory from the app/design/frontend directory and also delete the corresponding record from the theme table in the database. The theme:uninstall CLI command is only used for deleting themes thatare installed as Composer packages. Disabling the theme from the backend admin configuration does not delete the theme files or records, but only makes it unavailable for use. References: [Delete a theme], [theme:uninstall]

 To add the text Happy Birthday. to be translated inside an .html template, the developer should use the i18n binding. This binding allows the developer to specify the text as a string literal and translate it using the Magento translation mechanism. For example:

This will render the text as it is, or translate it if a translation file is available for the current locale. The i18n binding can also accept variables or expressions as arguments. For example:

This will render the text with the value of name variable, or translate it if a translation file is available for the current locale. The Mil8n and il8n bindings are not valid and will not work, as they are misspelled and do not match the knockout binding syntax. References: [Knockout bindings], [i18n binding]
