Problem statement: Answer the multiple-choice question.
Query: Which compound exhibits a 5.323\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a O=C(/C=C/c1ccc([N+](=O)[O-])cc1)c1ccco1
b CN(C)c1nc(OCc2ccccc2)c2ncc(=O)[nH]c2n1
c COc1ccc(/C=N/NS(=O)(=O)c2ccc(C)cc2)cc1
d O=C(O)c1ccc(N/N=C/c2ccc(-c3ccc(Cl)cc3Cl)o2)cc1
Answer: a. O=C(/C=C/c1ccc([N+](=O)[O-])cc1)c1ccco1
