Problem statement: Answer the multiple choice question.
Query: Which drug has a 16.438\% 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) COc1cc(NC(=O)c2cc([N+](=O)[O-])ccc2Br)ccc1NC(=O)c1ccco1
(b) O=c1nc(-c2ccccc2)n(-c2ccccc2)[nH]1
(c) C=CCn1c(-c2cccnc2Cl)nc2cc(Cl)c(Cl)cc21
(d) O=C(NC1CCCCC1)C1CC(=O)N(CCc2ccccc2)C1
(e) O=C(CN1CCC(C(=O)c2cccc(Cl)c2)CC1)Nc1ccc(C(=O)O)cc1
Answer: c. C=CCn1c(-c2cccnc2Cl)nc2cc(Cl)c(Cl)cc21
