Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 18.031% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: CCOC(=O)N1CCN(c2nc(C)nc3c2cnn3CCc2ccccc2)CC1
b: CCOC(=O)C(=O)C1=CN(Cc2ccccc2)C=C(C#N)C1
Answer: b. CCOC(=O)C(=O)C1=CN(Cc2ccccc2)C=C(C#N)C1
