Answer:
D.
Explanation:
Erik Erikson developed a theory of Psychosocial Development. The Psychosocial theory of development is an eight-stage theory from infancy to late adulthood.
Stage 6 of the theory, intimacy versus isolation, is a stage from 18-40. In this stage, people build intimate relationships with people around them. Successful development of relationships brings intimacy otherwise brings isolation.
In the given case, Peter who is 28, is in the 6th stage of psychosocial development. If Peter will marry his girl--friend then he will develop intimacy otherwise isolation.
Therefore, option D is correct.
