Best answer
Correct option is (c) getElementsbyTagName()

For explanation I would say: The getElementsByTagName() method returns a collection of all elements in the document with the specified tag name, as a NodeList object. The method getElementsbyTagName() can be used to get a particular value using the tagged name associated with the document.
