The correct answer is: drive.
The verb “drive” is used to describe the action of operating a motor vehicle. In Britain, people drive on the right side of the road. This means that when they are driving, they should keep to the right side of the road, and pass other vehicles on the left.
The other options are incorrect because they do not accurately describe the action of driving. Option A, “are driving,” is in the present progressive tense, which is used to describe actions that are happening right now. Option B, “drives,” is in the third person singular present tense, which is used to describe actions that are happening regularly or habitually. Option C, “drove,” is in the past tense, which is used to describe actions that happened in the past.
I hope this explanation is helpful!
