Task: Answer the multiple choice question.
Query: Which compound has a 16.853\% 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 additional words.
Options:
(a) O=[N+]([O-])c1ccc(N/N=C\c2ccccc2OCc2ccccc2)cc1
(b) Cc1noc2ncnc(Sc3ccccc3Cl)c12
(c) COc1ccc(CC(NC(C)=O)C(=O)NC2CCN(C(=O)c3ccc([N+](=O)[O-])cc3)CC2)cc1OC
(d) CCOc1ccc(S(=O)(=O)NCCC(=O)N2CC=C(c3ccccc3)CC2)cc1
(e) COc1ccc(NC(=O)CCCNS(=O)(=O)c2cccs2)cc1
Answer: a. O=[N+]([O-])c1ccc(N/N=C\c2ccccc2OCc2ccccc2)cc1
