Task: Answer the multiple choice question.
Question: Which drug has a 0.421\% 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 additional words.
Options:
a: O=C(C1CCCN(S(=O)(=O)c2cccc3nsnc23)C1)N1CCc2ccccc21
b: CC(C)CCn1c(Cl)nc2c1c(=O)n(C)c(=O)n2C
Answer: a. O=C(C1CCCN(S(=O)(=O)c2cccc3nsnc23)C1)N1CCc2ccccc21
