A is wrong because it is contradictory. 'B' is wrong because it is talking about future time whereas the part of the sentence given is referring to the past time. 'D' is wrong because when referring to past time, we would have to use the type of verbs found in the conclusion of a third condition, (I would have visited you), since, in fact the speaker did not visit the person being spoken to [Refer to the Answer Book to Effective English, pages 31-34. "I meant to visit you" in answer "C" means that I had intended or planned to visit you". This idea fits in perfectly with the idea expressed in the part of the sentence given in question 7 and C is, therefore, the answer.

After verbs or phrases showing doubt, ignorance or uncertainty (I doubt, I won- der. I am not sure, I do not know), the conjunctions "whether” or “if” are used to take the place of that to introduce a clause Note, however, that whether and if are not used to take the place of question words used as conjunctions (who, what, how, etc.).
Note:
I doubt whether (or if) Mary is home.
I wonder whether (or if) Mary is home. am not sure whether (or if) Mary is home.
There is some doubt whether Mary is. home.
There is no doubt that Mary is home, "There is no doubt is the opposite of "There is some doubt and therefore does not fit our definition that verbs or phrases showing doubt, etc. take whether? or 'if
