The three major categories of factors that influence our perception of another person include:

A) characteristics of ourselves, the target person, and the situation.
B) feeling, intuition, and sensing.
C) timing, availability, and consistency of information.
D) our own locus of control, the target person, and consistency of information.

The three major categories that influence our perception of another person are characteristics of ourselves (such as our beliefs, values, and experiences), the target person (such as their behavior and appearance), and the situation (context in which the interaction occurs). These factors collectively shape how we perceive and interpret others' actions and intentions.
