Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 16.510\% hERG inhibition at 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=C(Nc1ccc(S(=O)(=O)Nc2ncccn2)cc1)c1cccc(S(=O)(=O)N2CCCC2)c1
(b) CCC(=O)N1CCCc2cc(S(=O)(=O)N3CCN(c4ncccn4)CC3)ccc21
(c) CCOC(=O)C(=CNc1ccc(Cl)cn1)C(=O)OCC
(d) CC(C)(C)C(=O)N1CCN(c2ccc([N+](=O)[O-])cc2Cl)CC1
(e) O=C(C1CCCN(Cc2ccccc2F)C1)N1CCCCC1.O=C(O)C(=O)O
Answer: c. CCOC(=O)C(=CNc1ccc(Cl)cn1)C(=O)OCC
