Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a -2.199\% 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=C(NCc1ccco1)c1ccc(NS(=O)(=O)c2cccc([N+](=O)[O-])c2)cc1
[b] O=C(O)c1nn(CCSc2ccccc2F)c(=O)c2ccccc12
[c] COc1cccc(N2CC(C(=O)Nc3nnc(SCC(=O)Nc4ccc(NC(C)=O)cc4)s3)CC2=O)c1
Answer: b. O=C(O)c1nn(CCSc2ccccc2F)c(=O)c2ccccc12
