Task: Answer the multiple choice question.
Question: Which compound exhibits a -1.442\% 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, c, d, or e without using any additional words.
Options:
a.) O=C(CN(C(=O)c1cccc([N+](=O)[O-])c1)C1CCCCC1)Nc1ccc(Cl)c([N+](=O)[O-])c1
b.) CCc1ccc(N(CC(=O)NC2CCCCC2)C(=O)CNC(=O)c2ccco2)cc1
c.) CN1CCN(S(=O)(=O)c2cccc(C(=O)NCc3ccc(Cl)cc3)c2)CC1
d.) CCOC(=O)c1ccc(NC(=O)c2ccc3c(c2)OCO3)cc1
e.) COc1ccccc1-c1nnc(SCC(=O)NCc2ccco2)n1N
Answer: a. O=C(CN(C(=O)c1cccc([N+](=O)[O-])c1)C1CCCCC1)Nc1ccc(Cl)c([N+](=O)[O-])c1
