Explanation:

- Potential Energy: This energy is related to the position or configuration of an object, often in a gravitational field. It is not dependent on speed.

- Kinetic Energy: This is the energy of an object in motion. It is indeed directly proportional to the square of its speed, given by the formula: KE = 1/2 mv². It is a scalar quantity.

- Mechanical Energy: This is the sum of potential and kinetic energy in a system. It is not solely dependent on speed.

- None of these: This option is incorrect because one of the previous options is correct.
