Q
What does the addEventListener() method do in JavaScript for SVG animations?

Answer & Solution

Answer: Option A
Solution:
The addEventListener() method in JavaScript attaches an event listener to an SVG element, allowing developers to define actions or functions that are triggered when a specific event (such as click, hover, or keypress) occurs on the SVG element. This method enables interactivity and dynamic behaviors in SVG animations by responding to user interactions or other events and executing corresponding actions or animations programmatically.
