Task: Answer the multiple-choice question.
Question: Which drug exhibits a 21.757\% 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, b, or c without using any additional words.
Options:
a: CCOc1ccccc1N1CCN(C(=O)[C@@H]2CCCN2C2=NS(=O)(=O)c3ccccc32)CC1
b: O=P(O)(O)C(O)C(F)(F)C(F)(F)C(F)(F)C(F)F
c: Cn1nc([N+](=O)[O-])nc1N1CCN(c2ccc(F)cc2)CC1
Answer: b. O=P(O)(O)C(O)C(F)(F)C(F)(F)C(F)(F)C(F)F
