Task: Answer the multiple-choice question.
Query: Which drug exhibits a -43.613% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a CCOC(=O)c1cn(CC)c2cc(F)c(F)cc2c1=O
b CCOC(=O)c1ccc2c(c1)nc(C1CCN(S(=O)(=O)c3cccs3)CC1)n2CC
Answer: b. CCOC(=O)c1ccc2c(c1)nc(C1CCN(S(=O)(=O)c3cccs3)CC1)n2CC
