Task: Answer the MCQ question.
Query: Which drug has a 11.342\% 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) CCOC(=O)/C(C#N)=C1/C=C(C)c2ccccc2N1
(b) COc1ccc(N(C(=O)c2ccco2)C(C(=O)NC2CCCC2)c2ccncc2)cc1OC
(c) CN1C(=O)C(=Cc2ccc(N3CCOCC3)c([N+](=O)[O-])c2)C(=O)N(C)C1=O
(d) CCOc1cc(CNn2nnnc2N)ccc1OCC(=O)NC(C)(C)C
Answer: a. CCOC(=O)/C(C#N)=C1/C=C(C)c2ccccc2N1
