PT #23 Sec.3(LR) Q.23 - parallel flawed reasoning

[sg7007]

This is the highway safety/smoking problem.

(B) and (D) were my contenders. The correct answer is (B).

I can kinda see why (D) is wrong. If you have a better lap time for the breaststroke, then you might win more often by practicing it.

But, I don't see how (B) is parallel with the reasoning in the passage. Is the reasoning in (B) even flawed at all?

Please help me with this. Thanks!
