Question

Choose the appropriate preposition and fill in the blank:

I am sorry I have not written to you for so long. The reason ____ this is that I have been ill.

• A. of
• B. for
• C. to
• D. None

Answer 1

Answer: (B)

for

The given sentence indicates a sense of reasoning . Therefore 'for' is the suitable answer, since 'for' is used to indicate a sense of reasoning or cause. Thus option B is correct. On the other hand 'of' is used to show an essence of reference. Hence option A is incorrect. The preposition 'to' indicates a direction of something. Since the sentence speaks a sense of reasoning, 'to' is not appropriate in the given context. Thus option C is incorrect.

The completed answer thus becomes: I am sorry I have not written to you for so long. The reason for this is that I have been ill.
