Task: Answer the multiple choice question.
Query: Which drug exhibits a 22.021\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) CCOC(=O)C1CCN(c2cc3c(cc2NC(=O)c2ccccc2)n(C)c(=O)n3C)CC1
(b) CCOC(=O)C1=C(C)NC2=C(C(=O)CCC2)C1c1cc(OC)ccc1OC
Answer: a. CCOC(=O)C1CCN(c2cc3c(cc2NC(=O)c2ccccc2)n(C)c(=O)n3C)CC1
