Task: Answer the multiple choice question.
Question: Which compound has a 15.959\% 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(-n2c(N)c(C#N)c3ccc([N+](=O)[O-])cc3c2=O)cc1
(b) COc1ccc(CCNC(=O)C(CCC(N)=O)NS(=O)(=O)c2ccc(Cl)cc2)cc1OC
(c) COc1ccccc1/C=C(\C)C(=O)c1c(C)cc(C)[nH]c1=O
(d) COc1ccc(/C=N/NC(=O)CCc2n[nH]c(=O)[nH]c2=O)cc1O
Answer: b. COc1ccc(CCNC(=O)C(CCC(N)=O)NS(=O)(=O)c2ccc(Cl)cc2)cc1OC
