Answer:
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.

How oxygen is being transported?
About 97% of the oxygen used during breathing is delivered by red blood cells in the blood, while the remaining 3% dissolves in plasma. The pigment hemoglobin, which is found in RBCs, is what gives blood its red color. According to the partial pressures of oxygen, carbon dioxide, H+ concentration, and temperature, oxygen attaches to hemoglobin to create oxyhemoglobin. Up to 4 oxygen molecules can be carried by a single hemoglobin molecule. The optimum circumstances for the synthesis of oxyhemoglobin include low temperature, high H+ concentration, and oxygen partial pressure. In the alveoli, these criteria are satisfied. But in the tissues, the circumstances are different, and as a result, oxygen is separated from oxyhemoglobin.
