a) the sun makes energy on the inside.
b) the sun uses energy from the planets
c) the sun reflects energy of the stars.
d) the sun takes energy from outer space.

A. The Sun makes energy on the inside.

Explanation:

The Sun makes its own energy by the the process called Nuclear fusion. When two or more atomic nuclei fuse together to create different atomic nuclei the process is called Nuclear fusion. In Sun the hydrogen atoms are fused together to create helium.This releases the lot of energy.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
