Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a -6.439\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] O=c1/c(=C\c2ccc(F)cc2)sc2n1CCCN=2
[b] CCN(CC(=O)NCc1ccc(Cl)cc1)C(=O)COc1ccc(Cl)cc1Br
[c] O=C(NC1CCCCCC1)C1CCN(S(=O)(=O)c2cnc[nH]2)CC1
Answer: b. CCN(CC(=O)NCc1ccc(Cl)cc1)C(=O)COc1ccc(Cl)cc1Br
