Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 17.805\% 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 or b without using any other words.
Options:
[a] O=C(O)c1ccc([N+](=O)[O-])c2c1C(=O)c1ccccc1C2=O
[b] Cc1cc(C)cc(N(C(=O)CNC(=O)c2ccco2)C(C(=O)NC2CCCC2)c2cccnc2)c1
Answer: a. O=C(O)c1ccc([N+](=O)[O-])c2c1C(=O)c1ccccc1C2=O
