Solution : The correct option is  skin

A severe vitamin C shortage is the root cause of the disease scurvy. The body needs vitamin C to generate collagen, which is the substance that holds bones and muscles together and gives skin its elasticity. Anaemia, tiredness, internal bleeding, limb pain, swelling, sometimes gum ulcers and tooth loss are signs of the scurvy disease. Getting a lot of vitamin C in the diet is part of the treatment for the illness.
