Task: Answer the multiple choice question.
Query: Which drug has a 17.983\% 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) CS(=O)(=O)Nc1ccc2c(c1)C(=O)OC2
(b) CC(C)(C)N/N=C/c1c(O)n(-c2ccc(Cl)cn2)c(=O)c2ccccc12
Answer: a. CS(=O)(=O)Nc1ccc2c(c1)C(=O)OC2
