Please explain why is d right?

Again, we first analyze the argument core.

Conclusion: unless one overgeneralizes, there is no connection between plucking gray hairs and negative attitudes towards the elderly

Premises:
1 it's possible to like the elderly and not like impaired eyesight/hearing
2 holding negative attitudes towards old people because they are old is immoral
3 nothing immoral about disliking aspects of the aging process

(A) the "contention that...plucking gray hairs = negative attitude toward elderly" is the ASSERTION mentioned here, and yes, the author dismisses it. Eliminate.

(B) the whole series of premises can be seen as an appeal to reason (ie the author lays out a string of reasons and draws a conclusion)

(C) #2 above is a general principle

(D) should jump out at us immediately, regardless of our understanding of the other choices. No stereotypes about elderly were discredited.

(E) yes, #1 above is a distinction of attitudes.

so "negative attitudes" does not necessarily mean "stereotypes", right?"
