Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 7.338\% 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 other words.
Options:
a) O=C(O)c1ccc(-n2cncn2)c([N+](=O)[O-])c1
b) Cc1cc2nc(C)c(Cl)c(=O)n2[nH]1
c) CN1CCN(c2ccccc2/C=N/NC(=O)c2cccnc2)CC1
Answer: a. O=C(O)c1ccc(-n2cncn2)c([N+](=O)[O-])c1
