الاجابة :
The correct way to complete the sentence is: "By the time he arrived home, his dad had driven his car."
In this case, the past participle "driven" is used because it follows the past perfect tense "had." The past perfect tense is formed by using "had" + past participle to indicate an action that was completed before another past action (in this case, arriving home).
