Gregory is an impoverished african-american teen who finds school stressful but performs at a moderate level academically. he has no relationship with his father but has a close relationship with his mother and grandmother. which of these factors most increases his vulnerability to developing a mental disorder?

Answer / Explanation:

Referring back to the narrative of the question,  it was stated that Gregory finds school stressful and it is worthy of note that stress when in excess can lead to a mental disorder.

Another reason the the fact that he has no relationship with his father but has with his mother and grandmother. This will at a point make him tend to think that he is more suitable as a lady or woman and which might have a draining effect on his thinking nature and in the long run might lead to depression and then to a mental disorder.
