Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 2.032% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: COCCN(CCOC)Cc1c(C)[nH]c2ccccc2c1=O
b: Cc1c(Br)c([N+](=O)[O-])nn1CC(=O)Nc1sc2c(c1C(=O)OC(C)C)CCCC2
Answer: a. COCCN(CCOC)Cc1c(C)[nH]c2ccccc2c1=O
