Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 6.356\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: COC(=O)c1c(S(C)(=O)=O)nc(-c2ccccc2)[nH]c1=O
b: O=C(NCCN1CCCCC1)Nc1ccccc1Cl
Answer: a. COC(=O)c1c(S(C)(=O)=O)nc(-c2ccccc2)[nH]c1=O
