Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 14.823\% 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 other words.
Options:
[a] O=C(CSc1nnnn1-c1ccc(O)cc1)Nc1ccc(N2CCOCC2)c(Cl)c1
[b] C=CCSc1nnc(Cn2c(=O)sc3ccccc32)n1C
[c] O=c1c(-c2ccc(Cl)cc2)[n+]([O-])c2ccccc2n1O
Answer: c. O=c1c(-c2ccc(Cl)cc2)[n+]([O-])c2ccccc2n1O
