Task: Answer the multiple-choice question.
Question: Which drug exhibits a 7.954\% 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 additional words.
Options:
a) CC1CCCN(c2nc3ccccc3nc2C(C#N)S(=O)(=O)c2ccccc2)C1
b) Cc1ccc([N+](=O)[O-])cc1N/C=C1\CCc2ccccc2C1=O
c) CCOc1ccc(C(=O)Nc2ccc(N3CCCC3)cc2)cc1
d) CNc1ccc(Cl)cc1C(N)=O
Answer: b. Cc1ccc([N+](=O)[O-])cc1N/C=C1\CCc2ccccc2C1=O
