Task: Answer the multiple choice question.
Query: Which drug exhibits a -2.640\% 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: CCOC(=O)N1CCN(C(=O)c2cccc(NC(=O)c3ccco3)c2)CC1
b: CC(=O)c1c(C)[nH]c(C(=O)Nc2nc(-c3ccccc3)c(C)s2)c1C
Answer: b. CC(=O)c1c(C)[nH]c(C(=O)Nc2nc(-c3ccccc3)c(C)s2)c1C
