I think many people are trying hard to explain this while having the so-called "answer".
Some guys said that D is wrong because it says "the second is a claim that has been used in support of the plan but that the argument maintains
is inaccurate", they claimed that the BF2 part "
is not inaccurate".
Actually, the argument says that
Quote:
"It is true that adding the projected output of the new hydroelectric plants to the output that Hasaria can achieve now would be enough to meet the forecast demand for electricity. It will, however, take at least fifteen years to complete the project and by then the majority of Hasaria's current power plants will be too old to function at full capacity."
which means "even though it's true now, it won't be true in 15 years", so
BF2 part alone indeed is inaccurate.
While on the other hand, E says that "the second provides evidence that is used to support the argument's evaluation of that plan", on the contrary, the

is the evidence.
So IMO, the correct answer is D.
