Task: Answer the multiple choice question.
Query: Which drug exhibits a 12.196\% 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) Cc1nc2ncnn2c(N2CCN(C(=O)c3cccc(F)c3)CC2)c1Cc1ccccc1
(b) CCOC(=O)C(C)/C(C)=N/NC(=O)CCC(=O)Nc1cc(C)ccc1C
(c) CCCCNC(=O)C(=O)N/N=C/c1ccc(C(=O)OC)cc1
Answer: b. CCOC(=O)C(C)/C(C)=N/NC(=O)CCC(=O)Nc1cc(C)ccc1C
