The booking was made and the taxi was _______ a few minutes.
Explanation : Since ‘was’ is the helping verb here, main verb cannot be in its original form, hence, option 1 is not correct. Option 2 is also not making any sense as ‘at a few minutes’ is not correct. For option 3, grammatically, ‘was arriving’ is correct but again ‘arriving a few minutes’ doesn’t make any sense. Hence, option 4 is correct.
