Task: Answer the multiple-choice question.
Question: Which drug has a 16.388% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: COc1ccc(OC)c(C2NC(=O)CCC2[N+](=O)[O-])c1
b: N#C/C(=C(/O)CCl)c1nc2c(s1)CCc1ccccc1-2
c: Cc1ccc(NC(=O)c2cc([N+](=O)[O-])ccc2NCc2cccnc2)cc1Cl
d: O=C(NC1CCC(O)CC1)c1ccc(-c2ccc([N+](=O)[O-])cc2)o1
e: Cc1ccccc1Cn1nc(C)c(NC(=O)/C=C/c2cnn(C)c2)c1C
Answer: a. COc1ccc(OC)c(C2NC(=O)CCC2[N+](=O)[O-])c1
