Task: Answer the multiple choice question.
Query: Which drug exhibits a -2.996\% 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 CCOc1cc(/C=N/n2c(C)nc3ccccc3c2=O)ccc1O
b COC(=O)COc1ccc(C2NC(=O)NC(C)=C2C(=O)NCc2ccccc2)cc1OC
c CC(=O)Nc1ccc(NC(=O)C2(C)CC2(Cl)Cl)cc1
d O=C(NC1CCN(Cc2ccccc2)CC1)c1c(F)cccc1F
e Cc1cccc(C(CC(=O)O)NC(=O)C(F)(F)F)c1
Answer: b. COC(=O)COc1ccc(C2NC(=O)NC(C)=C2C(=O)NCc2ccccc2)cc1OC
