ATP-a phosphorylated nucleotide C10H16N5O13P3 composed of adenosine and three phosphate groups that supplies energy for many biochemical cellular processes by undergoing enzymatic hydrolysis especially to ADP. — called also adenosine triphosphate. Comments on ATP.
photosynthesis-the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

Answer:
A star can live for billions of years: Option A.
Explanation:
The given excerpt clearly indicates that a star can run out of hydrogen and energy only after millions or billions of years. Only then it collapses to a little ball with gravity. This means it would live till those millions or billions of years.
'Black hole' is a region in the space which has such strong gravitational force that it pulls every object that passes through it. Albert Einstein predicted that black star would exist if a dead star also had enough gravity. Hence, "option A" is the correct one.
