I think it comes down to what makes more sense:

"they are conserve energy" or "they do conserve energy"

Their windows(subject) are(verb) built to conserve energy, and they(subject) do(verb) [conserve energy]
Hence C.

I would pick C
Well what I think

the windows are built to conserve energy
it is a fact so we use the present form and
' They do' stand for they conserve the energy .

A wrong tenses use
B WRONG CONSTRUCTION
C ok
D ACKWARD with the use of being and have
E wrong use of past perfect

In this sentence the 'do' refers to the verb phrase 'conserve energy.' However, we do not have to repeat the 'conserve energy', as in, 'do conserve energy.' The ellipsis is the omission of the phrase 'conserve energy' as it is implied.

The verbs 'have' cannot function in this sense the way that the auxiliary verb 'do' does. In general when you want to refer back to a verb or a verb phrase, use 'do'.

Hope that helps .

I agree C is right. But I have a doubt. Does choice C still hold true if "are built" is replaced with "have been built"?

Hi csck.

Good question . We can't use present perfect "have been built" here because of the intended meaning.
The intended meaning is that the windows are able to conserve energy NOW. it means the windows are complete products. If you use "the windows have been built....", you mean the building process has not completed yet. If the building process has not completed, how the windows can conserve energy? (the windows are still in testing step, for example). Thus, only simple present tense - "are built" - is correct.

Hope it helps.
