Solution

The correct option is B Pellagra
Maize grains contain about the same amount of protein as other cereals (8 to 10 percent), but much of it is in the form of zein, a poor-quality protein containing only small amounts of lysine and tryptophan. The association noted between maize consumption and pellagra may be due to a deficiency of these amino acids. Whole-grain maize contains 2 mg niacin per 100 g, which is less than that in wheat or rice. The niacin in maize is in a bound form and not entirely available to humans. In Mexico and some other countries, maize is treated with an alkaline solution of lime which releases the niacin and helps prevent pellagra.
