C. Deductive reasoning

Explanation:

Deductive reasoning is a reasoning or logical process whereby a conclusion is drawn based on the belief of multiple premises that are generally assumed to be true. It is a logical process in which one or multiple statements reaches a logical conclusion.

In the question, the statement assumed to be true is that <em>noble gases are unreactive because of their electronic structures.</em>

The conclusion thus drawn from the premise is that <em>if other elements could be made to achieve noble gases electronic structures (</em><u><em>this is the reason why they are unreactive - the fact)</em></u><em> they would be more stable.</em>

<em />

Therefore, deductive reasoning moves from a wilder reasoning to a specific (narrower) reasoning.
