_____ involves describing one's position in ways that identify common ground and establish a collaborative tone.

A) Social proof
B) Credibility
C) Framing
D) Reciprocity

This is the definition of framing, which involves presenting information in a way that makes it more appealing and understandable to the audience. In this case, the goal is to establish common ground and a collaborative tone to foster cooperation and agreement. Social proof and credibility are related concepts, but they do not involve explicitly describing one's own position or perspective. Reciprocity refers to the idea of exchanging something of value or benefit, which is not directly related to the question prompt.
