A it is

it has clear referent
it refers to condition everywhere in the original sentence

Also, A does not changes meaning

cornily · Answer

I'd rather go for D
D respects parallelism and is clearer about the referent of "it" than A.
In A, it is not clear weather "it" refers to "the presence of a condition" or "a condition", whereas in D, there is no doubt that "a condition" is the referent.
OA?

Looks like B to me.What is the OA?

getmba · Answer

I would go with D.

Choice C and E out as "Fails to detect when" doesn't make sense.
Choice B inserts "there" which is not needed
Between A and D, A is wordy and has pronoun reference problem (it refers to what: presence or condition).

Left with D as the correct choice.
