Answer 2

a fact or example that reinforces the main idea

Step-by-step explanation:

A supporting detail refers to extra information that clarifies, provides reasons, describes or demonstrates the main idea, such as a fact or example.

The rest of the choices are incorrect because they do not necessarily justify, define or illustrate the most important thought in a straightforward manner.
