Task: Answer the multiple choice question.
Query: Which drug has a -2.390\% 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: Cc1oc(-c2ccccc2)cc1C(=O)Nc1ccc2ccccc2c1
b: O=[N+]([O-])c1ccc2cn(-c3ccccc3)nc2c1
Answer: b. O=[N+]([O-])c1ccc2cn(-c3ccccc3)nc2c1
