Task: Answer the multiple-choice question.
Query: Which drug has a 22.371\% 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 other words.
Options:
[a] O=C(CS(=O)(=O)c1ccc(Cl)c(Cl)c1)Nc1ccccc1Cl
[b] Cc1cc(N2CCC(C)CC2)nc2ccc(N3C(=O)CCC3=O)cc12
Answer: a. O=C(CS(=O)(=O)c1ccc(Cl)c(Cl)c1)Nc1ccccc1Cl
