Yes
Explanation:
Two isotopes of hydrogen, tritium and protium, undergo nuclear fusion in the sun to give helium, neutrons and a tremendous amount of energy. This reaction occurs at the very high temperature found in the sun and yields tremendous amount of energy.
Given the high temperature at which the said fusion reaction occurs, it is safe to say that hydrogen and helium act as a furnace at the core of the sun.
Option A and D are totally incorrect because the cell and mitochondria and chloroplast are co dependent on each other.
We can say that the eukaryotic cell provides protection to mitochondria and chloroplast and in turn they provide energy.
Option C is incorrect too because prokaryotes being inferior to Eukaryotes ,cannot engulf them.
So in my opinion option B should be correct because of endosymbiosis theory which says that Superior cells engulf the prokaryotes without digesting them. So that the prokaryotes living inside the eukaryote can provide it energy and the superior cell provides the protection to the inferior one.
hope u get it, thank you
