Official Explanation :

Choices A and B illogically compare the acid smoke of cigarettes with pipe tobacco, not with the smoke from pipe tobacco.

Choice B is also faulty for making the curing methods rather than the nature of the smoke the basis of comparison.

Choice C is best, for it compares cigarette tobacco with pipe tobacco in terms of the type of smoke each produces.

Choices A and B - illogical comparison.
