Task: Answer the multiple choice question.
Question: Which compound exhibits a -3.618\% 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] O=C(Nc1ccc(-n2cnnn2)cc1)c1ccc(Cl)c(S(=O)(=O)N2CCCC2)c1
[b] CC1CCCCC1NC(=O)C1CCC(CNS(=O)(=O)c2ccccc2)CC1
Answer: a. O=C(Nc1ccc(-n2cnnn2)cc1)c1ccc(Cl)c(S(=O)(=O)N2CCCC2)c1
