Task: Answer the multiple-choice question.
Query: Which drug has a 4.496\% 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) NS(=O)(=O)c1ccc(NC(=O)Nc2cccc(Cl)c2)cc1
(b) CCOC(=O)c1[nH]c(C)c(CN(CCc2ccccc2)S(C)(=O)=O)c1C
Answer: b. CCOC(=O)c1[nH]c(C)c(CN(CCc2ccccc2)S(C)(=O)=O)c1C
