Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -5.592% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) CCCCn1c(N)c(NCCC(C)C)c(=O)[nH]c1=O
(b) COc1cc(S(=O)(=O)NCCCN2CCOCC2)ccc1Cl
Answer: a. CCCCn1c(N)c(NCCC(C)C)c(=O)[nH]c1=O
