Answer:
d. the person
Explanation:
The real psychological, and then societal and cultural, implication of one's death is the leave of the person and the vacancy they leave in the society's structure.
<u>Each person has it's own place in the structure of the family, neighborhood, job, etc. and with death, the rest must learn how to cope with their leave and continue without implications.</u>
It is also notable that the body in most of the cultures is just the symbol of the person, while the real person is connected to their social role, identity and behavior, which they fulfill and have while alive. This is why in many cultures the death of the brain is taken as the "real" and legal death - <u>only the leave of the person's identity, social role and function is really what the environment misses with one's death.</u>
