Answer 2

Answer:

Option (1), (4), (6)

Explanation:

The energy possessed by the position or configuration of a body is called it's potential energy.

Gravitational potential energy is defined as the energy possessed by the height of object from the ground level.

Here, a person walks up on the flight of stairs has cover some height from the ground level, so it has gravitational energy.

Wind lifts a balloon in air also have gravitational potential energy.

Weightlifter lifts a barbell overhead also cover some height to lift the barbell, so it also have some gravitational potential energy.
