Task: Answer the multiple-choice question.
Question: Which drug exhibits a -9.396% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: Cc1ccc(S(=O)(=O)N2CCN(c3ccccc3)CC2)cc1C(=O)NC1CCCCC1
b: COc1cc(C2SCCS2)cc(Br)c1Oc1ncccc1[N+](=O)[O-]
c: COCc1c(Br)c(C)[nH]c(=O)c1C#N
d: CCc1ccc(C(=O)c2cc3ccc(O)cc3oc2=O)cc1
e: Cc1ccc(S(=O)(=O)NNC(=O)CCC(=O)Nc2ccccc2Cl)cc1
Answer: c. COCc1c(Br)c(C)[nH]c(=O)c1C#N
