Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -2.485\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: Nn1c(C2CCC2)nc2ccccc2c1=O
b: O=C(CN1C(=O)NC2(CCCCCC2)C1=O)c1ccc(F)cc1
Answer: b. O=C(CN1C(=O)NC2(CCCCCC2)C1=O)c1ccc(F)cc1
