A bullet from a gun and a monkey falling from a tree due to gravity both follow the same downward trajectory at the same acceleration rate, due to the force of gravity. This gravitational force affects all free-falling bodies in the same way, regardless of their horizontal velocities. So, even though the monkey lets go of the tree after the gun is fired, they are both pulling towards earth with the same acceleration.

Option 2 and 3 are incorrect because the bullet and the monkey are under the same gravitational force, the bullet won`t hit above or below the aimed point. It will instead hit the exact point it was aimed at.

Option 4 is also incorrect because, as stated above, the bullet and the monkey are moving downward at the same rate, so the bullet won`t miss the monkey.

Thus, the correct answer is option 1 - the bullet will hit the monkey at the point aimed at.
