Solution (By Examveda Team)

In the given options, all sentences except option D are in the simple future tense.

Option A: "Shall I open the window?" - This sentence is in the simple future tense and is formed using the modal verb "shall" to make a polite offer or suggestion in the future.
Option B: "You will do exactly as John says." - This sentence is in the simple future tense and uses the modal verb "will" to express a future action.
Option C: "He'll carry your luggage for you." - This sentence is in the simple future tense and uses the contracted form of "will" (he'll) to indicate a future action.
However, option D "You should have studied for your exams" is not in the simple future tense. It is in the present perfect tense, formed by using the modal verb "should have" to express regret or advice about a past action. In this case, the advice is about something that should have been done in the past (studying for exams) but was not done.

Therefore, the correct answer is option D, and the sentences in the simple future tense are A, B, and C.
