Explanation:
Verbal Communication simply refers to a form of oral communication whereby the transmission of message is done through spoken words. In this case, the sender expresses his or her feelings, or opinions through conversations, speeches, or discussions.
Based on the question, the assumption does Christopher make about lying and verbal communication refers to the fact that our actions are worth more than our words. Through our actions and behavior, we can tell lies. For example, if someone says he'll do something and doesn't do it later, it simply means the person told a lie through his action.
The assumption that Christopher makes is that only those who talk lie.
