It's in passive voice.
A good rule of thumb for cases like this is that if it has any variation of the verb "to be" (is, was, were, etc.) it's passive voice.
If you wanted to switch it to active voice you need to get rid of "is", and this is usually done by switching the subject and the object (so while in the original sentence, the race car is the doing the verb, to switch it you'd need to make the sixteen-year-old boy be the one doing the verb). This new sentence would be something like:
The sixteen-year-old boy drove the racecar
I think around 6pm (Thursday) but you might want to double check me on that!
The correct answer is A. We slowed down because of the road's sudden bumps.
This is because all of the other answer options are incomplete sentences or fragments. Answer A is the only grammatically proper sentence.
