Task: Answer the MCQ question.
Query: Which compound has a 0.942\% 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=S(=O)(Nc1nccs1)c1cc(Cl)ccc1Cl
b O=c1cc(N2CCc3ccccc32)[nH]c(=O)n1-c1ccccc1Cl
Answer: a. O=S(=O)(Nc1nccs1)c1cc(Cl)ccc1Cl
