Problem statement: Answer the multiple choice question.
Query: Which drug has a 2.850\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a. CCOc1ccccc1NC(=O)/C(C#N)=C/c1c(C)nn(-c2ccc(F)cc2)c1Cl
b. COC(=O)C1=C(C)N(CC(C)C)C(=O)C1
Answer: b. COC(=O)C1=C(C)N(CC(C)C)C(=O)C1
