Problem statement: Answer the MCQ question.
Question: Which compound exhibits a 13.925\% 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 or b without using any additional words.
Options:
a CC(C)=N/N=C(\c1cccc([N+](=O)[O-])c1)C12CN3CN(CN(C3)C1)C2
b O=C(NC(=S)Nn1cnc2c(cnn2-c2ccccc2)c1=O)c1ccc(Cl)cc1
Answer: a. CC(C)=N/N=C(\c1cccc([N+](=O)[O-])c1)C12CN3CN(CN(C3)C1)C2
