Problem statement: Answer the multiple-choice question.
Query: Which compound exhibits a -6.813\% 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: Cc1cc(CNC(=O)c2ccc(C)c([N+](=O)[O-])c2)c2ccccc2n1
b: O=C(NC1CCSc2ccccc21)c1ccc([N+](=O)[O-])cc1
c: O=[N+]([O-])c1cccc(-c2cnc3ccccc3n2)c1
Answer: b. O=C(NC1CCSc2ccccc21)c1ccc([N+](=O)[O-])cc1
