The caffeine in coffee stimulates the production of irritating acid in the stomach. But darker roast s of coffee, produced by roasting the coffee beans longer, contain more N-met hylpyridinium (NMP) than lighter roast s, an d NMP tends to suppress production of acid in the stomach. Therefore if you drink caffeinated coffee, darker roast s will irritate your stomach less than lighter roasts.

The answer to which one of the following questions most helps in evaluating the argument ?

(A) Does extending the roasting time of coffee beans increase the amount of caffeine present in the brewed coffee?
(B) Does a reduction in acid production in the stomach have an adverse effect on stomach function ?
(C) Would coffee drinkers who drink caffeinated coffee increase their coffee consumption if the coffee they drank contained less caffeine?
(D) Do some coffee drinkers who switch from lighter to darker roasts of coffee increase their daily coffee consumption?
(E) Do lighter roasts of coffee have any important health benefits that darker roasts of coffee lack?

A is the correct choice
Caffeine stimulates acid production.
If on roasting amount of caffeine increases then it will nullify the effect of increased amount of NMP.

The answer to the B will tell us about its effect on stomach functions.
But here we have to analyse whether it will decrease the irritation by reducing the acid production which is caused by caffeine.
