Task: Answer the multiple choice question.
Question: Which drug exhibits a 8.331\% 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(=O)N/C(=N\c1nc(C)cc(C)n1)Nc1ccc2ccccc2c1
b) CCOC(=O)c1cc(=O)n2c(nc3ccccc32)[nH]1
c) CCOC(=O)c1c(C)nc(C(Cl)(Cl)Cl)nc1N
d) C=CCc1cccc(C=Nc2ccc(Br)cc2)c1O
e) COc1ccc(NC(=O)CSc2ccc3nnc(-c4ccccn4)n3n2)cc1
Answer: b. CCOC(=O)c1cc(=O)n2c(nc3ccccc32)[nH]1
