This question is testing VERB TENSES. When you see differences in verb tense in answer choices, ask yourself: "when are these events happening in time?"
The intended meaning of the sentence should be:
- light left these quasars long in the past
- we're just seeing that light now
Quasars are so distant that their light has taken billions of years to reach the Earth; consequently, we see them as they were during the formation of the universe.
(A) we see them as they were during
- simple present tense for what we see now
- simple past tense for what these quasars were like in the past
(B) we see them as they had been during
- the past perfect "had been" should only be used in relation to another past tense event: "it had been X before Y happened." Since the only other event in this sentence is present tense, the past perfect is not appropriate.
(C) we see them as if during
- "as if" is hypothetical, but this really happened
- "as if during" doesn't locate the formation of the universe in a different time period to the present moment. It's more logical to use the past tense here.
(D) they appear to us as they did in
- the logical extension of this comparison is "they appear to us (now) as they did (appear to us) at the beginning of the universe" - in other words, it implies that we were there at the beginning of the universe. Illogical!
(E) they appear to us as though in
- similar to C - this is hypothetical and present-tense. We need to situate the formation of the universe as an actual event in the past.
The answer is A.
