HERE IS OE
This sentence describes the consequences when the human body's intake of carbohydrates drops below a certain level: below that point, the body begins to metabolize fat rather than glucose (a state called ketosis). The opening part of the sentence should clearly and properly indicate the conditions described, i.e., the carbohydrate intake itself is sufficiently low. The two different sources of fuel mentioned in the sentence – fat and glucose – should be written in parallel.
(A) The usage of both “sufficiently” and “enough” is redundant; the modifier beginning with “where…” illogically suggests that ketosis is a physical location. Finally, "metabolizes fat directly" is not parallel to “using glucose.”
(B) The plural verb “are” does not agree with the singular subject “intake”; the two constructions “fat is directly burned” and “metabolizing glucose” are not parallel. Finally, the pronoun it seems to refer (illogically) to “intake.” (“Human body's” is an adjective, not a noun, so it can't be the antecedent of that pronoun.)
(C) CORRECT. “In the case of a sufficiently low carbohydrate intake” correctly delineates the circumstances under which the described effect is observed. The present tense (“enters”) is appropriate, because the sentence describes a general phenomenon. The pronoun “it” is properly used to refer to the human body, and the appositive modifier “a state…” is properly used to modify ketosis. Finally, the parallel structure X rather than Y is properly formed with two nouns (“fat rather than glucose”).
(D) The modifier beginning with “where…” illogically suggests that “cases” are physical locations.
(E) “Sufficient” is misplaced, suggesting that the carbohydrate intake itself must be “sufficient,” rather than sufficiently low.
