Both of these could absolutely be correct. "Which" is a singular subject of "is"; while "grapes" is plural and "melon" is singular, they are logically and grammatically parallel and the verbs agree appropriately. You actually wouldn't need the "does" in #2, but it could still be correct with or without it.

GMATKiss produces three very nice sentences above, which are also correct, but none of them is more correct enough to be preferable on the GMAT. That is, although #2 is shorter, the original #2 doesn't have any real wordiness errors that the GMAT tests, so you'd never see those two choices with no other differences between them.

If "is" goes well with "which" then how come they can use "songs". is melon and grapes are parallel?
