Problem statement: Answer the multiple choice question.
Question: Which drug has a 18.720\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a CC(C)[C@H](NS(=O)(=O)c1ccc2c(c1)OCCO2)C(=O)OCC(=O)Nc1ccccc1Cl
b CCOP(=O)(OCC)C(NC(C)=O)C(=O)c1ccccc1
Answer: b. CCOP(=O)(OCC)C(NC(C)=O)C(=O)c1ccccc1
