Before coming into conclusion first we have to understand potential energy.The potential energy of a body is defined as the energy possessed by a body due to its position and configuration.
There are generally two types of potential energy.One is gravitational potential energy and the other one is elastic potential energy.The former one is due to the position of the body at a certain height from the surface of earth.The latter one is due to the change in configuration of the body.
There is also electric potential energy which is stored inside the electric filed of charge particles at rest.
The first example is holding a basket ball in air.As the body is at certain height from earth surface ,hence it has gravitational potential energy which is a best example of potential energy.
The second one is a rolling ball across a flat table.It has both rotational kinetic energy due to its rolling motion as well as potential energy due to its position.
The third one can't be considered as it is electric in nature.
The fourth one is turning on a flashlight in a dark room.The light is due to the heating effect of electric current. so it is not gravitational in nature.
Hence option one is the correct answer.
The car is heavier than a person
