Q
Which statement accurately describes JavaScript event bubbling?

Answer & Solution

Answer: Option A
Solution:
JavaScript event bubbling refers to the upward propagation of events from child elements to parent elements in the document tree. When an event occurs on a nested (child) element, it also triggers the same event on its parent elements, propagating upwards until reaching the root (document).
