Task: Answer the multiple choice question.
Query: Which drug has a 3.953\% 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(N)=N/OC(=O)C2CCC(=O)N2S(=O)(=O)c2ccc(C)cc2)cc1
(b) CC(C)(C)OC(=O)NCC(=O)Oc1cc2oc(=O)cc(-c3ccccc3)c2cc1Cl
(c) COc1ccc2c(c1)c(CC(=O)Nc1ccc(C(C)=O)cc1)c(C)n2C(=O)c1ccc(Cl)cc1
(d) c1ccc(CCCN2CCOCC2)cc1
Answer: c. COc1ccc2c(c1)c(CC(=O)Nc1ccc(C(C)=O)cc1)c(C)n2C(=O)c1ccc(Cl)cc1
