Task: Answer the multiple choice question.
Query: Which drug exhibits a 7.995\% 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: CCC(=O)N/C(=N/c1nc(C)cc(C)n1)Nc1ccccc1
b: O=C1C2C(C(=O)N1/N=C/c1ccc([N+](=O)[O-])o1)C1C=CC2C12CC2
Answer: b. O=C1C2C(C(=O)N1/N=C/c1ccc([N+](=O)[O-])o1)C1C=CC2C12CC2
