Touch-based communication varies depending upon the type of:

A) tone.
B) speech rate.
C) pitch.
D) relationships.

Touch-based communication is highly influenced by the nature of the relationship between the communicators. A touch can be interpreted differently depending upon the type of relationship. For example, touching someone's hand can be a sign of affection or intimacy between two romantic partners, but the same touch can be viewed as inappropriate or unwelcome between strangers or professional colleagues. Therefore, touch-based communication varies depending upon the type of relationship.
