Task: Answer the multiple-choice question.
Question: Which compound has a 3.189\% 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] COc1ccc(CN(CC(=O)NC2CCCC2)C(=O)c2onc(C(N)=O)c2N)cc1
[b] Cc1cc(C)c(S(C)(=O)=O)c(S(=O)c2ccc(Cl)cc2)n1
Answer: b. Cc1cc(C)c(S(C)(=O)=O)c(S(=O)c2ccc(Cl)cc2)n1
