Answer

The ball takes more time to come back to the ground.

Work Step by Step

If the air resistance is taken into account then we know that the air resistance does negative work on the ball during its downward journey. As a result, its kinetic energy is decreased which means that its speed is decreased. Thus, the ball takes more time to come back to the ground.
