Answer:
Fantasy
Explanation:
Sigmund Freud considered Fantasy a defence mechanism from the ego.
Stating we cannot subsist on the scanty satisfaction which they can extort from reality. 'he sees fantasy a construction around several , often repressed wishes, and uses disguise to cover and serve the defensive processses by which desire is enacted. The ego desire to carry or modify reality is a way of sublimating anxiety. The use of fantasies make anxiety levels decrease and coping with reality is possible.
The repressed wishes often are unconscious linking from the beginnings of interaction and sexuality between a child and a mother, often the initial scen of fantasy is created when the frustrated infants involve the milk, the mothers' breast closely linked to instincts.
Interesting is to notice that the child experiences the primary fantasies by associating these experiences with objects and circumstances and then they form in the unconscious level.
However daydreaming is another conscious mechanism where someone distorts reality in an effort to relieve the anxiety, and it was also studied by Freud and his followers .
The correct answer is preening behavior.
Preening behavior or simply preening is described as a body language or series of unconscious/uncontrollable gestures between two persons, who are interacting, which signals attraction to each other.
