Problem statement: Answer the multiple choice question.
Question: Which compound has a 5.532\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a) COC1=CCC2([N+](=O)[O-])CN(C)CC1([N+](=O)[O-])C2
b) NS(=O)(=O)c1ccc(CCNc2nc(-c3cccnc3)nc3ccccc23)cc1
c) CC1(C)C(=O)OC(C(=O)c2ccccc2)C2(CCCCC2)C1=O
Answer: a. COC1=CCC2([N+](=O)[O-])CN(C)CC1([N+](=O)[O-])C2
