C. Useful energy out of a system is always less than the energy input of that system.
Explanation:
The correct statement of the given options is that useful energy out of a system is always less than the energy input of that system.
This is in compliance with the third law of thermodynamics which states that "energy transformation in a system is not 100% efficient".
- At every stage energy is usually lost when it is transformed from one form to another.
- There is no machine that is 100% efficient.
- A machine that is 100% efficient will convert all the useful energy in it to do work and even more.
- In system energy is usually lost as a result of heat and to overcome friction.
- This reduces the amount of energy out of a system.

In my opinion
Mass extinctions happen because of climate change, asteroid impacts, massive volcanic eruptions or a combination of these causes. One famous mass extinction event is the one that lead to the extinction of dinosaurs, 65 million years ago.

<span>In this case, all these statements are true. Salinity is the salt in the water. Jacques Piccard and Lt. on Walsh were the first people to explore the deepest part of the worlds ocean known as the Mariana Trench in The Challenger Deep, and Jason 1 is a satellite released by NASA to monitor world ocean circulation and study the way the atmosphere and ocean interact with each other to improve the predictions for the climate when it comes to major weather events like El Nino.</span>
