Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 1.365\% 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) COc1ccc(CNC(=O)Cn2nc([N+](=O)[O-])c(Br)c2C)cc1
b) NNC(=O)CNC(c1ccccc1)c1cc(Br)ccc1NC(=O)c1ccc(Br)cc1
c) Cc1nc2ccccn2c1C(=O)N/N=C/c1ccccc1Cl
Answer: a. COc1ccc(CNC(=O)Cn2nc([N+](=O)[O-])c(Br)c2C)cc1
