Lawrence and Sophia are on a double date with Sophia's cousin and his girlfriend. As the discussion turns to Sophia's mother, Lawrence gets a bit nervous, as he knows Sophia's mother does not like him dating her daughter. When Sophia's cousin asks how it is going, Sophia says, "Oh, she adores him and wants to know when the wedding is". She pats Lawrence's leg and winks at him as she says this, to let him know she is joking. Lawrence understands how Sophia wants him to interpret her message because nonverbal communicationA. serves multiple functions.
B. metacommunicates.
C. is present in most communication situations.
D. is the primary means of expressing emotion.

Meta-communication is the form of communication which needs to be interpreted because the message or communication may or may not mean the same as conveyed.

In the given situation, Lawrence needs to understand the meta-communication spoken by Sophia because what she said about her mother's feelings towards Lawrence is not true. But she winks and pats Lawrence's leg to convey that she is communicating which needs to be understood by him.

So, the correct answer is Option B.
