Logical reasoning question help

If Larry drives to work in the morning, he will hit traffic. Therefore:

A) If Larry hits traffic, it must be morning.
B) If Larry drives to work in the afternoon, he will not hit traffic.
C) If Larry doesn't hit traffic, it must not be morning.
D) If Larry drives to work in the afternoon, he will hit traffic.
E) None of the above.

I would like to understand the answer.

I am thinking answer would be E.

Conditional logic is pretty simple:
If the left side is happening, then you know the right side is happening.
If the right side isn't happening, then you know the left side isn't happening.

GIVEN:
If he drives to work in morning, he will hit traffic

THE ONLY OTHER THING WE CAN SAY IS
If he doesn't hit traffic, then he didn't drive to work in the morning.

So (E) would be correct.
