The survey showed that children are much more psychologically stable

Only A and D maintain parallelism.

"where" in A is wrong imo.

Answer: D

....in a family with X than in a family with Y
So cancel B,C & E
Between A & D ....in A ,intended meaning is also changed by using 'and' before 'cares'
Ans D

MANHATTAN REVIEW OFFICIAL EXPLANATION:

The first thing you want to look at in this sentence is parallel structure. Because you say in the beginning ‘raised in a family’, you have to maintain the singular form of family. That eliminates choices C and E as possible answers. Also, the parallel structure carries over to prepositions. In the beginning, it says ‘raised in a family of x than in a family of y’. You have to maintain that structure of ‘in a family’. That leaves you with two possible choices: A and D. A uses the word ‘where’, which is incorrect. ‘Where’ refers to locations. The placement of ‘only’ in A and E is incorrect. It implies that the only thing this parent does is to care for a child. Choice D is the correct answer
