A Correct answer
Explanation

ActionScript uses the 'extends' keyword for class inheritance, following Java's syntax. The correct declaration is 'public class MyButton extends Button'. Option B uses 'becomes' which is not valid. Option C uses 'inherits' which is not ActionScript syntax. Option D uses 'implements' which is for interfaces, not class inheritance.
