The correct answer is D. He wondered where he would be that time the following year.
The sentence “Where shall I be this time next year!” is an expression of uncertainty or speculation about the future. The speaker is wondering where they will be in one year’s time. This is a common thought that people have, as it is natural to be curious about what the future holds. The speaker may be thinking about their career, their relationships, or their overall life situation. They may be hoping to be in a different place in one year’s time, or they may be content with where they are now. Whatever the case may be, the speaker is clearly thinking about the future and wondering what it holds.
Option A is incorrect because the speaker is not asking a question. They are expressing their thoughts and feelings about the future.
Option B is incorrect because the speaker is not wondering where they should be. They are wondering where they will be.
Option C is incorrect because the speaker is not contemplating. They are expressing their thoughts and feelings.
