Task: Answer the multiple choice question.
Query: Which drug has a 19.027\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: O=C(CSc1nc(-c2ccccc2)c(-c2ccccc2)o1)Nc1nnc(-c2ccccc2)s1
b: CCN(CC)C(=O)COc1coc(CN2CCN(Cc3ccccc3)CC2)cc1=O
Answer: a. O=C(CSc1nc(-c2ccccc2)c(-c2ccccc2)o1)Nc1nnc(-c2ccccc2)s1
