Answer 2

Answer:

A. Emotion; memory.

Explanation:

Emotion and memory encompasses all the other choices.

Let's define both concepts:

• Emotion: an innate feeling, consequence of situations which determines an individual's mood and behavior.
• Memory: the capacity to retain and remember information.

Situations carry a strong sentimental value for an individual and the stronger the harder it is to forget the situation per se as well as the emotions that came with it.

Both terms influence an individual's thoughts and behaviors; conscious . and unconsciously and determine how he/she will respond to future situations and to life in general.
