Task: Answer the multiple-choice question.
Query: Which compound has a 15.414\% 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) O=[N+]([O-])c1ccc(NCc2ccc(Cl)cc2)nc1
(b) COc1ccc(NC(=O)C2CC(c3c(F)cccc3Cl)=NO2)cc1
(c) CCCn1c(N)c(C(=O)CN(C)CC(=O)Nc2ccccc2C(F)(F)F)c(=O)[nH]c1=O
(d) COc1ccc([C@H]2CC(=O)C=C(c3ccc(Cl)c(C(F)(F)F)c3)C2)cc1
(e) CC(=O)Nc1ccc(NC(=O)CSc2ccc(-c3cccnc3)nn2)cc1
Answer: a. O=[N+]([O-])c1ccc(NCc2ccc(Cl)cc2)nc1
