    Answer:

    He should aim it at the monkey

    Explanation:

    The question is related to projectile motion of an arrow from a bow such that the arrow is able to reach a specific target

    Therefore, since the monkey is going to drop from the tree the instant the person launches the food, then for the monkey to be able reach the food, we have;

    Final level position of the launched food should be ≥ The level of the monkey

    As the monkey is dropping from the tree the destination of the launched food should be at the monkey so that before the food gets to the position where the monkey was when launching the food with the arrow, the monkey will be slightly lower so as to be able to catch the food or return up the tree to get the food rather than the food falling to the ground.
