Answer: 3. C. mitochondrion
Explanation:
Mitochondrion in a cell is defined as the powerhouse of the cell which provide energy to the whole cell. 
A mitochondrion is has a membranous layer and bean-shaped organelle that is the “energy transformer” of the cell. They contibute to the  biochemical processes of the cell called cellular respiration. They works as a digestive system which takes nutrients, breaks them into several energy rich molecules for the cell.
Hence, the correct answer is 3. C. "mitochondrion".
 
        
             
        
        
        
Aerobic respiration takes place in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy. 
anaerobic respiration also produces energy and uses glucose but it produces less energy and does not require oxygen.
