Caffeine, such as that in coffee, must still be administered by the relatively cumbersome process of brewing and drinking. If caffeine is drunk, some of the caffeine gets partially digested and cannot reach the brain to cause alertness. However, certain inhaled non-caffeine stimulants contain magnetized elements, which are not subject to separation through digestion.

The statements above most strongly support a claim that a research procedure that successfully accomplishes which of the following would be beneficial to users of caffeine as a stimulant?
Choices

A) Turning coffee into a gaseous cloud of magnetized elements that is absorbed directly by brain cells.
B) Using proven laboratory procedures, converting into caffeine-like compounds the non-caffeine stimulants that may be inhaled.
C) Removing any chemicals that digest caffeine permanently from the stomach and intestine.
D) Systematically categorizing what separating enzymes and polypeptides exist normally in the digestive tract and how each tends to be absorbed by the body.
E) Timing the length of time that each non-caffeine stimulant takes to get to brain cells.

The OA is A. To me it looks dubious. The stimulus only talks about the magnetic elements method being beneficial for non-caffeine stimulants. In saying that option A is correct, the question composer at Grockit is bringing out of scope considerations into the question.

This is the official explanation for option C, which I had chosen - "Choice C is not the correct answer. This statement is contradictory; permanently removing everything that digests caffeine would be harmful."

Please tell me if I am wrong
