Personality types in the Myers-Briggs Type Indicator are defined by A) four categories, represented as letters. 

Explanation:

"The Myers-Briggs Type Indicator is based on the conceptual theory proposed by Carl Jung, who had speculated that humans experience the world using four principal psychological functions – sensation, intuition, feeling, and thinking – and that one of these four functions is dominant for a person most of the time."

- Where you focus your attention – Extraversion (E) or Introversion (I) 
- The way you take in information – Sensing (S) or Intuition (N)
- How you make decisions – Thinking (T) or Feeling (F)
- How you deal with the world – Judging (J) or Perceiving (P)
