Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 4.589\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] CCC(=O)Nc1cc(-c2nn(C)c(=O)c3ccccc23)ccc1N1CCOCC1
[b] CC(=O)c1cn(CCNc2ncc(C(F)(F)F)cc2Cl)c(=O)[nH]c1=O
[c] CCN(c1ccccc1)S(=O)(=O)c1ccc(Oc2ccc([N+](=O)[O-])cc2)nc1
[d] COc1ccc(-c2nn(CC(=O)NCCc3ccccc3)c(=S)n2C)cc1
Answer: c. CCN(c1ccccc1)S(=O)(=O)c1ccc(Oc2ccc([N+](=O)[O-])cc2)nc1
