Task: Answer the multiple-choice question.
Query: Which drug exhibits a 13.692\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) CCOC(=O)Nc1c(C(=O)OC)[nH]c2cccc(OC)c12
(b) CC(C)Cc1nnc(NC(=O)C23CC4CC(CC(C4)C2)C3)s1
(c) COc1cc(NC(=O)c2cc(-c3ccco3)on2)c(OC)cc1Cl
Answer: a. CCOC(=O)Nc1c(C(=O)OC)[nH]c2cccc(OC)c12
