Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a -0.226\% 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 COc1ccc2cc(/C(C)=N/NC(=O)C3CC3)ccc2c1
b CCC(C)C(NC=C1C(=O)OC(C)(C)OC1=O)C(=O)O
Answer: b. CCC(C)C(NC=C1C(=O)OC(C)(C)OC1=O)C(=O)O
