B Correct answer
Explanation

Mitochondria are known as the powerhouses of the cell because they generate adenosine triphosphate (ATP), which the cell uses as a source of chemical energy. They perform cellular respiration to convert nutrients into usable energy. Chloroplasts produce energy in plants via photosynthesis, but mitochondria are the universal powerhouses in both plant and animal cells.
