B is the correct option because, in a cell, <u>only mitochondria</u> generate and provide <u>energy</u> for muscle movement.
Explanation:
Mitochondria are known as a powerhouse of the cell because they perform <u>cellular respiration</u> and <u>generate energy as an ATP</u> (Adenosine Triphosphate) molecule. <u>Muscle cells function in movement and burn more energy that's why they have many mitochondria to fulfill energy demands.</u>
On the other hand, options <u>A, C, and D are not correct options </u>because mitochondria do not perform other services such as acting as protein factories, linker cells, nutrients transportation. The activities are performed by other organelles.
