crux is the last Q.
Use 310/5.7 as reference = 54.xx To get a lower HP per L, we either need lower HP, or larger L or both. My approach is:
1) filter the table by HP, you see only four cars fewer HP than 310. all of them have materially lower Engine size, with a quick math 300/4.6 also larger than 54.
2) filter by engine Size, you see a range of car at the bottom more than 5.7L, amongst which the smallest HP and biggest L is 400/6.2 = obviously 60 -> confirm Tesco has the lowest ratio.

Tesco has the least price, but PTZ has a lower ratio.
I think OA is wrong.

Statement 1: The model with the smallest engine and at least one other model both rank last in the amount of horsepower they produce.
Explanation: Olsen Model have the smallest engine size of 3 as well as the least amount of horsepower is produced by Olsen as well as PTZ and Granato. So first statement is true.
Statement 2: The lightest model produces the most horsepower per pound of vehicle weight.
Explanation: Biota is the lightest weight model which produces less horsepower per pound of vehicle weight at least 2 other models, hence the statement is False.
Statement 3: The model with the lowest dollar-per-horsepower ratio is also the model with the lowest price.
Explanation: T-400 model has the lowest dollar-per-horsepower ratio, while the model with the lowest price is Tesco, Hence the statement is False.
