Task: Answer the multiple choice question.
Query: Which compound has a -1.661\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a CN(C)C(=O)CSc1nnc(C23CC4CC(CC(C4)C2)C3)o1
b O=C(c1nc(SCc2ccc([N+](=O)[O-])cc2)n2ccccc12)C(F)(F)F
c Cc1nc(N)sc1N=Nc1ccc(F)cc1
d Cc1ccc(C(=O)OCC(=O)NNC(=O)c2ccccc2)c(O)c1
Answer: c. Cc1nc(N)sc1N=Nc1ccc(F)cc1
