Task: Answer the multiple-choice question.
Query: Which drug exhibits a 20.249\% 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 Nc1nnc(SCC(=O)OCC(=O)c2ccccc2Br)s1
b Nc1[nH]c(=O)[nH]c(=O)c1N=Nc1ccccc1Cl
Answer: b. Nc1[nH]c(=O)[nH]c(=O)c1N=Nc1ccccc1Cl
