Task: Answer the multiple-choice question.
Query: Which drug exhibits a 5.386\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a COc1ccc(NC(=O)C2CCCN2S(=O)(=O)c2ccc3c(c2)CCC(=O)N3)cc1Cl
b CN(CC(=O)Nc1ccccc1Br)C(=O)c1ccc(COc2ccccc2)cc1
c COc1ccc(C2=NCCn3nc4cc([N+](=O)[O-])ccc4c32)cc1
d O=C(N/N=C/c1c(O)n(C2CCCCC2)c(=S)[nH]c1=O)c1ccccc1O
e O=C(CSc1n[nH]c(=O)[nH]c1=O)c1ccc([N+](=O)[O-])cc1
Answer: c. COc1ccc(C2=NCCn3nc4cc([N+](=O)[O-])ccc4c32)cc1
