Task: Answer the multiple choice question.
Query: Which compound has a 21.605% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a O=C(Nc1cc([N+](=O)[O-])ccc1F)c1ccc2c(c1)OCCO2
b Cc1ccc(NC(=O)N2CCCC2C(=O)NCC2CCCO2)cc1
Answer: a. O=C(Nc1cc([N+](=O)[O-])ccc1F)c1ccc2c(c1)OCCO2
