Task: Answer the multiple choice question.
Query: Which drug exhibits a -0.131\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] NNc1nc2cc3c(cc2s1)OCCO3
[b] O=C(CNC(=O)c1ccc(S(=O)(=O)N2CCCC2)cc1)N/N=C/c1ccccc1Cl
[c] O=Cc1sc(Nc2ccccc2)nc1Cl
[d] CC(C(=O)N1CCN(Cc2ccccc2)CC1)c1ccc([N+](=O)[O-])cc1
[e] O=C(CNC(=O)c1ccc(Cl)cc1Cl)NCC1CCCO1
Answer: c. O=Cc1sc(Nc2ccccc2)nc1Cl
