Task: Answer the multiple choice question.
Question: Which drug exhibits a 8.909\% 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] CC(C)(CN1CCc2ccccc2C1)NS(=O)(=O)c1ccc(Cl)cc1
[b] Cc1ccc(OCCC(=O)OCC(=O)c2c(N)n(C)c(=O)n(C)c2=O)cc1
Answer: a. CC(C)(CN1CCc2ccccc2C1)NS(=O)(=O)c1ccc(Cl)cc1
