Task: Answer the multiple-choice question.
Query: Which drug exhibits a 4.944\% 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) O=C(CC(c1ccccc1)c1ccccc1)Nc1nn[nH]n1
b) O=C(CN1C(=O)C2C3C=CC(C3)C2C1=O)Nc1nc(-c2ccccn2)cs1
Answer: b. O=C(CN1C(=O)C2C3C=CC(C3)C2C1=O)Nc1nc(-c2ccccn2)cs1
