Task: Answer the multiple choice question.
Question: Which drug exhibits a 3.086\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
(a) CCOc1ccc(C(N)=O)cc1OC
(b) O=c1cc(CO)oc(CN2CCC(Cc3ccccc3)CC2)c1O
(c) Cc1cc(C)c(S(=O)(=O)c2ccccc2C)c(OCC(C)(C)C)n1
(d) Cc1ccccc1C(=O)Nc1ccc(C(=O)NNC(=O)CCCOc2ccc(Cl)cc2Cl)cc1
(e) CCOC(=O)CSC1=C(C#N)C(=O)NC2(CCCCC2)S1
Answer: a. CCOc1ccc(C(N)=O)cc1OC
