Task: Answer the multiple-choice question.
Question: Which drug has a 6.784\% 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: CC(=O)N1N=C(c2ccccc2O)CC1c1cccs1
b: O=C(NNc1c(Cl)cccc1Cl)C1CCC1
Answer: a. CC(=O)N1N=C(c2ccccc2O)CC1c1cccs1
