The law of conservation of energy, first formulated in the nineteenth century, is a law of physics. It states that the total amount of energy in an isolated system remains constant over time. The total energy is said to be conserved over time. For an isolated system, this law means that energy can change its location within the system, and that it can change form within the system, for instance chemical energy can become kinetic energy, but that energy can be neither created nor destroyed.

Explanation:
The statement given in the question is incorrect. It should be "According to the principle of conservation of momentum, the total momentum of a system of masses in any direction remains constant unless acted upon by an external force in that direction."
Conservation of Energy:
- The principle of conservation of energy states that the total energy of an isolated system remains constant.
- Energy can neither be created nor destroyed, it can only be transferred from one form to another.
- The total energy of the system before a process is equal to the total energy of the system after the process.
Conservation of Momentum:
- The principle of conservation of momentum states that the total momentum of an isolated system remains constant.
- Momentum is defined as the product of mass and velocity.
- The total momentum of a system can only change if an external force acts on the system.
Conclusion:
Hence, the correct option is B) False. The statement in the question is incorrect and refers to the principle of conservation of momentum, not energy.

This is conservation of momentum. for eg in case of collision if it is inelastic than there is a loss of energy but momentum remains constant.
