The correct answer is Vitamin A.
Vitamin A is a fat-soluble vitamin that is essential for good vision, skin, and the immune system. It is found in animal products such as liver, eggs, and dairy products, as well as in some plant-based foods such as carrots, sweet potatoes, and dark leafy greens.
Night blindness is a condition in which people have difficulty seeing in dim light. It is caused by a deficiency of vitamin A, which is necessary for the production of rhodopsin, a protein in the retina that is essential for vision in low light.
Vitamin B is a group of water-soluble vitamins that are essential for energy production, cell function, and the nervous system. They are found in a variety of foods, including meat, poultry, fish, eggs, dairy products, legumes, nuts, and seeds.

Vitamin K is a fat-soluble vitamin that is essential for blood clotting and bone health. It is found in green leafy vegetables, broccoli, Brussels sprouts, and liver.
