Answer:
Moods D. Function mostly to bias cognitions and what the person thinks about.
Explanation:
A mood is an emotional state; it's the sentimental tone an individual attributes to an idea or situation, which can be either pleasant or unpleasant.
As it is a state, it is a way of being for the individual which is maintained for a period of time and eventually fades, which can take hours or days, for example.
Emotions come and go but unlike them, one's mood is bias to cognitions, to the way an individual interprets his/her environment and what he/she thinks about.
