Task: Answer the multiple choice question.
Question: Which drug exhibits a -8.884\% human ether-à-go-go related gene (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) CCOC(=O)N1CCN(c2cc(=O)n(-c3ccc(C)cc3)c(=O)[nH]2)CC1
(b) O=C(CN1C(=O)NC2(CCCc3ccccc32)C1=O)NCc1ccco1
Answer: a. CCOC(=O)N1CCN(c2cc(=O)n(-c3ccc(C)cc3)c(=O)[nH]2)CC1
