‘Declarative Knowledge’ in learning grammar refers to ________.

The correct answer is "knowing the rules of a grammatical item."

Explanation:

In language learning, Declarative Knowledge refers to explicit knowledge about language rules, structure, and concepts. It is the conscious knowledge of "knowing that" or "knowing what"—for example, understanding the rules of syntax, verb tenses, and grammatical structures.

On the other hand, Procedural Knowledge refers to "knowing how"—the ability to put that grammatical knowledge into practice fluently and automatically when speaking or writing.

Therefore, knowing the rules of a grammatical item is classified as Declarative Knowledge.
