Answer 1

Hint:Tenses refer to the time of action and allows the user to determine whether the action is still going on, has it completed, is it going to happen, and so on. Tenses can be classified into three main categories - Present, past, and future, of which each has subdivisions of their own. The simple past tense of the verb refers to the time that has passed for some time. The sentence requires the past tense of the verb since the action took place sometime in the past.

Complete answer:
Now, considering the above options,
 Haven’t slept: is the present perfect form of the verb. There is no need to use the present perfect since the action is already in the past and done with. It indicates that the action has already taken place once or numerous times. The time here is usually indefinite. Eg: I haven’t talked to you in ages.

Am not sleeping: The first sentence depicts that the action is in the past. So, present continuous tense needn’t be used in this circumstance. Eg: I am not sleeping on the couch.

 Didn’t sleep: is the form of the verb which is apt for this sentence since it describes the verb in the simple past tense, an action that is not likely to repeat in the near future. The time given here is definite and can be classified as past tense. Eg: I didn’t sleep well last night due to all the noise downstairs.

Was not sleeping: Past continuous is often referred to circumstances such as an interrupted action, parallel actions, and specific time given as an interruption Eg: She was not sleeping despite the fact that she was exhausted. Here, such a tense is not required.

Hence, Option c is the best answer to the above sentence given in the question.

Note:
The sentence refers to simple past tense and not past continuous tense. Hence, eliminate the option “was not sleeping” as one is not supposed to change the tense.
