Complete answer:
In the given question, we have to find out which of the given options includes the answer in past continuous tense as it is the tense used to describe actions and states continued in the past period of time.
Let us thus analyze the options given to us in this question-
Option (a.), 'hadn’t rain', refers to ‘hadn’t’ which is in perfective tense. Therefore, option (a.) is incorrect as we need the answer in the past continuous tense.
Option (b.), ‘didn’t rain', refers to ‘rain’.
Therefore, option (b.) is incorrect as it could only have been correct if the first statement indicated that the raining had stopped in the past, and was not going on in the future.
Option (c.), ‘wasn’t raining', refers to past continuous tense.
Therefore, option (c.) is correct as we needed past continuous tense since this sentence describes actions and states continued in the past period of time (raining).
Option (d.), ‘isn’t raining', refers to present continuous tense. Therefore, option (d.) is incorrect as we need the answer in the past continuous tense.

Note:
In this question, it will be helpful for the student to recall the concept of tenses. Tense is a grammatical category of verbs used to express distinctions of time. There are three tenses - past, present, and future.
