Option 1 - Rickets: Rickets is a condition that occurs in children when they don`t get enough vitamin D, calcium, or phosphate. Vitamin D is produced by the body when the skin is exposed to sunlight. Therefore, children who receive very little sunshine, especially in western countries with limited sunlight, may be at higher risk of developing rickets. Rickets causes weak and soft bones, leading to deformities such as bowed legs, stunted growth, and skeletal abnormalities.

Option 2 - Dermatitis: Dermatitis refers to inflammation of the skin and is not directly related to the lack of sunshine in western countries.

Option 3 - Scurvy: Scurvy is caused by a severe deficiency of vitamin C and is not associated with the lack of sunshine.

Option 4 - Kwashiorkor: Kwashiorkor is a form of severe malnutrition, typically caused by a lack of protein in the diet, and is also not related to the lack of sunshine.

Therefore, the correct answer is option 1 - rickets.
