Task: Answer the multiple choice question.
Question: Which compound has a -5.327\% 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(Nc1cc(-c2ccccc2)sc1C(=O)O)c1cccc(F)c1
b CCCCC(=O)Nc1c2c(nn1-c1ccc([N+](=O)[O-])cc1)CS(=O)(=O)C2
c O=c1[nH]c(=O)n(CCc2ccc(F)cc2)c(O)c1C=NCCCn1ccnc1
Answer: b. CCCCC(=O)Nc1c2c(nn1-c1ccc([N+](=O)[O-])cc1)CS(=O)(=O)C2
