Task: Answer the multiple-choice question.
Question: Which compound has a 11.428\% 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) NS(=O)(=O)c1ccc(NC(=O)COC(=O)c2ccc([N+](=O)[O-])s2)cc1
b) COc1cc(CNC(C)c2ccccc2)c(Br)cc1OCC(N)=O
c) COC(=O)c1cccc(NC(=O)Cc2ccc(OC)cc2)c1C
Answer: a. NS(=O)(=O)c1ccc(NC(=O)COC(=O)c2ccc([N+](=O)[O-])s2)cc1
