A: If the intake of carbohydrates is sufficiently low enough, the human body will enter ketosis, where it metabolizes fat directly rather than using glucose.
B:
If the human body's intake of carbohydrates are sufficiently low, it will enter ketosis, a state in which fat is directly burned rather than metabolizing glucose.
C:
In the case of a sufficiently low carbohydrate intake, the human body enters ketosis, a state in which it directly metabolizes fat rather than glucose.
D:
In cases where carbohydrate intake is low enough, the human body will enter ketosis, in which fat rather than glucose is directly metabolized.
E:
If the sufficient intake of carbohydrates is low enough, the human body will enter ketosis, in which its metabolism burns not glucose but fat.
In A and E,
sufficiently/sufficient and
enough are redundant. Eliminate A and E.
In B,
intake (singular) does not agree with
are (plural). Eliminate B.
In D,
where cannot be used to refer to CASES;
where can refer only to a place. Eliminate D.
The correct answer is
C.
In C, there is no doubt about the referent for IT:
The human body enters ketosis, a state in which IT directly metabolizes fat rather than glucose.
Here,
a state is in APPOSITION to
ketosis.
Nouns in apposition refer to the SAME THING:
ketosis =
a state.
Thus, if IT were referring to
ketosis, then the meaning conveyed would be the following:
KETOSIS is a state in which KETOSIS directly metabolizes fat.
This meaning makes no sense.
Further, the referent for
which is
A STATE, which in turn refers to
KETOSIS.
How could
which and
it --two adjacent pronouns -- be referring to the same thing?
Clearly, IT refers to THE HUMAN BODY:
Ketosis is a state in which THE HUMAN BODY directly metabolizes fat.
