Which of the following methods would you use to remove a child node?

1. deleteChild()

2. removeChild()

3. detachChild()

4. dropChild()

The correct answer is: removeChild()

The method to use for removing a child node in the Document Object Model (DOM) is removeChild(). This method is part of the Node interface and allows you to remove a specified child node from a parent node. To use this method, you first need to call it on the parent node and pass the child node you want to remove as an argument. This effectively removes the specified node from the parent, ensuring that it is no longer part of the document tree. The other methods listed do not exist in the DOM API for node manipulation. deleteChild() and detachChild() are not standard methods available in the DOM, while dropChild() is also not recognized as a valid method for managing child nodes. Thus, only removeChild() is the correct and functional choice for this task.
