Answer:

The correct answer is option A which is Strap a boulder to the car so that it weighs more.

Explanation:

The gravitational potential energy of an object can be described as the energy due to the position of the car.

It usually depends upon the height of the car from the ground and its weight.

Higher the weight more the gravitational potential energy as well as higher the distance between the car and earth surface more the potential energy.

Gravitational potential energy = mgh

Hence here the correct statement about increasing the gravitational potential energy is option A.

Answer:

Strap a boulder to the car so that it weighs more

Explanation:

Gravitational potential energy is calculated using PE = mgh. If more gravitational potential energy is desired, simply increase the mass of the object or the height of the object from the ground or both! Strapping a boulder to the car so that it weighs more is the only situation that will increase the mass or height and; thus, the gravitational potential energy.
