Task: Answer the multiple choice question.
Question: Which drug has a 10.562\% human ether-à-go-go related gene (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: CCOC(=O)C1=C(C)OC(N)=C(C#N)C1c1cc(F)ccc1F
b: CCN(C(=O)CN1C(=O)NC2(CCCc3ccccc32)C1=O)c1ccc(F)cc1
Answer: b. CCN(C(=O)CN1C(=O)NC2(CCCc3ccccc32)C1=O)c1ccc(F)cc1
