Task: Answer the multiple choice question.
Query: Which drug exhibits a 16.988\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: Cc1cc(NS(=O)(=O)c2cn(C)nc2C)no1
b: CC1CCN(S(=O)(=O)c2ccc(NC(=O)C3CSC4(C)CCC(=O)N34)cc2)CC1
c: Cc1nc(SCc2ccccc2)c2ccsc2n1
d: COCCN(Cc1cc2cc(C)ccc2nc1Cl)C(=O)Nc1ccccc1OC
e: COc1ccccc1CN(Cc1cc2c(C)ccc(C)c2[nH]c1=O)Cc1nnnn1Cc1ccco1
Answer: c. Cc1nc(SCc2ccccc2)c2ccsc2n1
