Solution

The correct option is D Pellagra
When an infected person coughs or sneezes, rubella spreads. The common cold is spread by breathing infected secretions from contaminated surfaces or by direct contact with infected secretions from contaminated surfaces. When someone gets a cold or touches their nose and then touches someone or anything else, this is known as person-to-person transmission. The influenza virus can spread to humans in three ways: 1) by direct contact with infected people; 2) through contact with contaminated objects (called fomites, such as toys and doorknobs); and 3) through inhalation of virus-laden aerosols.
Pellagra is deficiency disease.
