I think the answer is D. As it is raining now, so I am driving right now.

DinoPen · Answer

I said A for this one.

I and II are related. And, III and IV are related.
Starting with I and II
The argument is the following:
All wheeled conveyances on the highway -> p
pollute -> q

If p -> q
~ q (bicycles are not polluters)
Therefore, ~p (bicycles don't go on the highway)

Now, looking at the III and IV:
Whenever I drive my car on the highway, it rains.
The argument is the following:
A: If I drive my car on the highway
B: it rains

A -> B
B
Therefore A.

This is not valid. Hence, take out C.

Manasvi1 · Answer

(A) Bicycles do not travel on the highway.   Correct   (according to question all vehicles that travel on the highway are polluters and bicycles are not polluters.)

(B) Bicycles travel on the highway only if it is raining.   Out of context   (In the question there is no mention that bicycle travels on highway only if it is raining)

(C) If my car is not polluting, then it is not raining.    Out of context   (In the question there is no relation between car, pollution and rain)

(D) I am now driving on the highway.   Incorrect   (In the question it is given that it is raining and whenever I drive on the highway it rains. But, it is not given that whenever it rains I drive on the highway)

(E) My car is not a polluter.    Incorrect   (In the question it is mentioned that car travels on highway. Also, it is a wheeled conveyance.Therefore, it must be a polluter)

Hence, answer is A

I. All wheeled conveyances that travel on the highway are polluters.
