The correct choice is (a) isEqualNode()

Easiest explanation: The method isEqualNode() is used to test if two nodes are equal. Two nodes are equal when they have the same type, defining characteristics (for elements, this would be their ID, number of children, and so forth), its attributes match, and so on.
