Task: Answer the multiple choice question.
Question: Which drug has a 4.145\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) CC(=O)N=C1C=CC(=CN(O)C(C)(C)Cc2ccccc2)C=C1
(b) CCN(CC)CCOC(=O)c1c(C)n(C)c2ccc(OC)cc12.Cl
Answer: b. CCN(CC)CCOC(=O)c1c(C)n(C)c2ccc(OC)cc12.Cl
