Problem statement: Answer the MCQ question.
Question: Which drug exhibits a -11.223% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: Fc1ccccc1/C=N/NC(=S)Nc1ccc(Cl)cc1Cl
b: CC1=NN(C(C#N)c2cccc([N+](=O)[O-])c2)C(C)(C)C1
c: O=C(O)CC1C(=O)NCCN1CCCc1ccccc1
d: C/C(=N/NC(=O)c1cc(-c2cccc([N+](=O)[O-])c2)n[nH]1)c1ccc(Cl)cc1
Answer: b. CC1=NN(C(C#N)c2cccc([N+](=O)[O-])c2)C(C)(C)C1
