(A) by further exercise is
(B) from further exercise are
(C) in furthering exercise are
(D) by exercising further would be
(E) by exercising even more would be
Choice A: This answer choice uses the idiomatically incorrect phrase "derive by". Additionally, this answer choice features a subject-verb disagreement between "benefits" and "is". Thus, this answer choice is incorrect.
Choice B: This answer choice maintains subject-verb agreement and proper idiom and tense use throughout the sentence; moreover, it also preserves the intended meaning of the sentence. Thus, this answer choice is correct.
Choice C: This answer choice uses the idiomatically incorrect phrase "derive in". Additionally, this answer choice changes the meaning of the sentence; the phrase "in furthering exercise" refers to the act of advancing the concept or practice of exercise, rather than increasing the amount of exercise that one participates in. Thus, this answer choice is incorrect.
Choice D: This answer choice uses the idiomatically incorrect phrase "derive by". Additionally, this answer choice uses the simple future tense, rather than the simple present tense, to refer to a universal truth. Thus, this answer choice is incorrect.
Choice E: This answer choice repeats the errors seen in Option D. Thus, this answer choice is incorrect.
Hence, B is the best answer choice.To understand the concept of "Simple Tenses on GMAT", you may want to watch the following video (~1 minute):
