• B. Starved
• C. Killed
• D. Defaecated
• E. Copulated

Answer 1

The correct option is A Exhausted

• Glucose is the major source of energy in the body. excess glucose is stored in the form of glycogen in muscles and liver.
  
• Most of the glycogen is stored in liver i.e 10 % of the mass of liver and the muscles contain a low amount of glycogen i.e 1% of the muscle mass.
  
• When the glucose is completely utilized the animal feels exhausted, to overcome this the glycogen is degraded to lactic acid by enzymes in muscles and liver.
• So, the correct answer is 'Exhausted'.
