Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 21.807% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a Cc1ccc(S(=O)(=O)CCC(=O)Nc2nnc(-c3ccccc3S(C)(=O)=O)o2)cc1
b O=C1Nc2ccccc2C1=Nc1cccc([N+](=O)[O-])c1
c COc1ccc(C)cc1NC(=O)Nn1cnnc1
d CCc1nc(SCC(=O)Nc2ccc3c(c2)OCCO3)c2oc3ccccc3c2n1
Answer: b. O=C1Nc2ccccc2C1=Nc1cccc([N+](=O)[O-])c1
