Task: Answer the multiple-choice question.
Question: Which drug exhibits a 8.945\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] CC(C)CC(=O)Nc1ccc2ccccc2c1
[b] CCOC(=O)COc1ccc2ccccc2c1/C=C/[N+](=O)[O-]
[c] O=C(Nc1cccc(Cl)c1)N1CCN(C/C=C/c2ccccc2)CC1
[d] CCOC(=O)c1ccc(NCCOC)c([N+](=O)[O-])c1
[e] C/C(=N\NC(=O)C(N)=O)c1ccc(O)cc1O
Answer: b. CCOC(=O)COc1ccc2ccccc2c1/C=C/[N+](=O)[O-]
