A Correct answer
Explanation

DOM (Document Object Model) loads the entire XML document into memory as a tree structure, allowing bidirectional navigation, search, and modification of elements. This makes it ideal for scenarios requiring user interaction like searching and editing. SAX is event-based, read-only, and processes the document sequentially without preserving the document structure in memory, making it unsuitable for editing operations.
