Step-by-step explanation:
Source credibility is indeed the extent to which a speaker is perceived as competent to make the claims he or she is making. The concept of credibility is often broken down into three components, namely expertise, trustworthiness, and goodwill. A source with high credibility is seen as knowledgeable (expertise), honest (trustworthiness) and empathetic (goodwill).
