Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 12.403\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a O=C1c2ccc([N+](=O)[O-])cc2C(=O)N1c1ccc([N+](=O)[O-])cn1
b O=C(NCc1cccnc1)c1cccc(S(=O)(=O)N2CCCCC2)c1
c CCn1c(-c2ccccc2)csc1=Nc1ccc(S(=O)(=O)O)cc1
Answer: a. O=C1c2ccc([N+](=O)[O-])cc2C(=O)N1c1ccc([N+](=O)[O-])cn1
