Problem statement: Answer the multiple-choice question.
Question: Which compound exhibits a 6.480\% 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, or d without using any other words.
Options:
a COc1ccccc1NC(=O)Cn1cnc2sc(C(=O)NCc3ccco3)c(C)c2c1=O
b CN(C)c1nc(C(=O)Nc2ccccc2)nc(N(C)C)n1
c O=C(CNC(=O)c1ccc(F)cc1)N/N=C/c1ccc(O)c([N+](=O)[O-])c1
d COC(=O)c1cn(NC(=O)c2cc([N+](=O)[O-])ccc2F)c(=O)c2ccccc12
Answer: c. O=C(CNC(=O)c1ccc(F)cc1)N/N=C/c1ccc(O)c([N+](=O)[O-])c1
