I have a question for you, experts:

the rules say that we can use either "agree with a person" or "agree upon/to something". That said I think that the correct answer should be

B)to which there was general agreement, that we could not give the Japanese any warning, that we could not concentrate on a civilian area, but

If the rule is true, we couldn't say " there was general agreement on a conclusion", but "to a conclusion".

What do you think?
