Task: Answer the multiple-choice question.
Question: Which drug has a 22.534\% 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: CCOc1cc(N2CCOCC2)c(OCC)cc1NC(=O)COC(=O)[C@H](Cc1c[nH]c2ccccc12)NC(C)=O
b: O=C(CN(C(=O)CCC(=O)Nc1nccs1)c1ccc(F)cc1)NCc1ccc(F)cc1
Answer: b. O=C(CN(C(=O)CCC(=O)Nc1nccs1)c1ccc(F)cc1)NCc1ccc(F)cc1
