Task: Answer the multiple choice question.
Query: Which drug exhibits a 7.566\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] O=C(Nc1ccccc1[N+](=O)[O-])c1cccnc1Cl
[b] CCOC(=O)CON1C(=O)c2ccccc2C1=O
[c] C/C(=N\NC(=O)COc1cccc(Br)c1)c1ccc2c(c1)OCCO2
[d] O=C(Cn1nc(-c2ccccc2)ccc1=O)N1CCOCC1
[e] COCCCNC(=S)N1CCCN(c2nc3cc(C)c(C)cc3cc2C#N)CC1
Answer: a. O=C(Nc1ccccc1[N+](=O)[O-])c1cccnc1Cl
