Task: Answer the multiple choice question.
Query: Which drug has a 17.948\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: CCOCCCNC(=O)C1CC(=O)N(CCc2ccccc2)C1
b: O=C(CN1CCCC1=O)NC1(C(F)(F)F)NC(=O)N(Cc2ccccc2)C1=O
Answer: b. O=C(CN1CCCC1=O)NC1(C(F)(F)F)NC(=O)N(Cc2ccccc2)C1=O
