Hello there!

The correct answer is D.

Hope This Helps You!
Good Luck :)

Answer: Option D

Explanation:

Earth is not considered as a closed in the reference that the energy from the volcanoes, earthquakes and hot springs are not returned back to these systems.

The energy from the earth's interior are released in the form of energy. Energy along with matter flows in different parts and is not recycled.

This proves that Earth is not a closed system when it comes to energy.
