Complete answer:
In the given question, we have to find out which of the options given to us is in the past continuous tense as ‘while’ is using when an action is said to be happening.
Let us thus analyze the options given to us in this question-
Option (a.), 'was parking', refers to the past continuous form of ‘park’. Therefore, option (a.) is correct.
Option (b.), ‘will park', refers to the future tense form of ‘park’. Therefore, option (b.) is incorrect as we need the past continuous form of ‘park’.
Option (c.), ‘park', refers to the basic verb ‘park’ in the present tense. Therefore, option (c.) is incorrect as we need the past continuous form of ‘park’.
Option (d.), ‘have parked', refers to the past perfect tense form of ‘park’. Therefore, option (d.) is incorrect as we need the past continuous form of ‘park’.
