Task: Answer the multiple choice question.
Question: Which drug exhibits a -50.456\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] O=C(COc1ccc(NC(=O)c2ccccc2[N+](=O)[O-])cc1)c1ccc(F)cc1
[b] CCCCC(=O)NNC(=O)c1c(O)c2ccccc2[nH]c1=O
[c] COc1ccc(N2CCN(CCCNC(=O)Nc3ccccc3)CC2)cc1
[d] O=C(Nc1ccc(N2CCN(C(=O)c3ccco3)CC2)cc1)c1ccccc1F
Answer: c. COc1ccc(N2CCN(CCCNC(=O)Nc3ccccc3)CC2)cc1
