Answer 2

C. Evidence

Step-by-step explanation:

Evidence refers to anything presented (a document, a witness testimony, tangible things, facts, etc.) that supports or disproves an assertion. So, if a speaker wants to convince a listener that their thoughts are worth considering, or that they are valid or well grounded, they need to present something that supports those thoughts: evidence.
