Task: Answer the multiple-choice question.
Query: Which drug exhibits a 13.690\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) O=c1cc(-c2ccccc2)[nH]n1-c1ccc([N+](=O)[O-])cc1
(b) CCc1ccc(Oc2nnnn2-c2ccc(C(N)=O)cc2)cc1
(c) Cc1ccc(NC(=O)CN(C)C(=O)/C=C/c2cccs2)cc1
(d) Nn1c(SCC(=O)Nc2ccc3c(c2)OCO3)nnc1-c1ccccc1
(e) Cc1c(Br)c([N+](=O)[O-])nn1CC(=O)NCCc1ccc(Cl)cc1
Answer: b. CCc1ccc(Oc2nnnn2-c2ccc(C(N)=O)cc2)cc1
