@ Atulmangal : Can you mention in both the cases below where do you see SUbject Verb agreemlnt or you wrote this in haste ? Certinaly, this is somethiung you dont want ..

quail eating will sometimes make .. where do you see S-V agreement in this ?

--->Eating quail SINGULAR make PLURAL VERB, doesn't agree
(D) It has long been known to Europeans that quail eating will sometimes make

Answer should be A for this question. @ original poster, can you put your doubts specifically ?
D is wrong for two reaons : 1> Future tense is incorrect 2> 'quail eating ' is incorrect . It should be 'eating quail ' .

Fish eating is good for health . (incorrect)

I'll go with A. What's the source?
