Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 12.591\% 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)c1cn(CC)c2cc(N3CCN(C)CC3)c(F)cc2c1=O
[b] Cc1ccc(NC(=S)N/C(=N/S(=O)(=O)c2ccccc2)c2ccccc2)cc1
Answer: a. CCOC(=O)c1cn(CC)c2cc(N3CCN(C)CC3)c(F)cc2c1=O
