Task: Answer the multiple-choice question.
Query: Which compound has a 18.188\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) COc1ccc(/C=C/C(=O)OCC(=O)Nc2ccc3[nH]c(=O)[nH]c3c2)cc1OC
(b) CNC(=O)c1c(NC(=O)c2cccc(C)c2)sc2c1CCC2
(c) COc1ccc(N(CC(=O)NC2CCCC2)C(=O)c2ccc(C)s2)cc1OC
(d) CC(/C=C/c1ccccc1)=N/NC(=O)c1cccc(Br)c1
Answer: c. COc1ccc(N(CC(=O)NC2CCCC2)C(=O)c2ccc(C)s2)cc1OC
