The rational functions in Jungian theory are __________.

A) thinking versus feeling
B) intuition versus sensation
C) judging versus perceiving
D) extraversion versus introversion

The rational functions in Jungian theory refer to the cognitive processes involved in decision making and perception. Thinking and feeling are two of these functions, representing different ways of processing information and making decisions based on logical analysis or emotional response. Intuition and sensation represent the other two functions, which involve processing information through unconscious perception or sensory experience. Judging and perceiving are not considered rational functions in Jungian theory, but rather describe different orientations to the external world. And extraversion and introversion refer to where a person tends to focus their attention and energy, rather than a specific cognitive process.
