Task: Answer the multiple choice question.
Question: Which drug exhibits a 0.553\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a.) Cn1ccc(C(=O)N/N=C/c2ccccc2[N+](=O)[O-])n1
b.) CN(CCOc1ccccc1)Cc1nc2cc(Cl)ccc2c(=O)[nH]1
c.) CC(C)=NOCC(=O)Nn1c(COc2ccccc2)nc2ccccc2c1=O
d.) O=C(Nc1cccnc1)Nc1cc(Cl)cc(Cl)c1
e.) CCOc1ccc(NC(=O)c2ccc(N3CC4CC(C3)c3cccc(=O)n3C4)c(N)c2)cc1
Answer: b. CN(CCOc1ccccc1)Cc1nc2cc(Cl)ccc2c(=O)[nH]1
