The correct answer is T (True)
Explanation:
The sun is one of the main or primary sources of energy; the sun produces large amounts of energy due to nuclear fusion reactions, and this energy reaches the Earth through radiation. This radiation is essential for plants and life.
Besides this, the sun is an essential or ultimate source for energy because electricity can be obtained through this; also, the sun causes air currents that are necessary for eolic energy and the sun regulates the water cycle necessary to obtain energy from water. This implies the sun is a massive source of energy and thus, it is true the sun is the ultimate source for energy on the Earth.
