If it is a long questionnaire, then it must be asking for a significant amount of personal information. The first blank needs to have something to do with a large quantity. The only word that fits that requirement is “plethora.” “Divulged” also works for the second blank. The purpose of any questionnaire is to get one to divulge information. By the way, notice the first word in (C): “phenomena.” The indefinite article “a” precedes the first blank, so the word following “a” must be singular. “Phenomena” is the plural form of “phenomenon.” The answer is (A).
