The Correct Option is A

Solution and Explanation

 Sexual cycle. The causative agent of malaria is P.vivax. It has two phases: the sexual phase takes place in the female Anopheles mosquitoes and the asexual phase takes place in the RBC of the host. The mosquitoes inject sporozoites that will enter the bloodstream of humans. The sporozoites travel to the cells of the liver and multiply asexually. The cells then ruptures so that the merozoites are released into the bloodstream.

Common Diseases in Human Beings

Any adverse variation from an organism's normal structural or functional condition is usually associated with specific signs and symptoms and distinct from physical injury.

  • Acute Disease

A few diseases appear out of nowhere and persist only a few days. Acute diseases, such as the common cold, are examples of them. Acute diseases frequently become chronic if they are not treated.

Acute diseases include strep throat, fractured bones, appendicitis, influenza, pneumonia, and others.

  • Symptoms and Treatments

Acute diseases develop quickly and are accompanied by unique symptoms that necessitate immediate or short-term treatment and improve once treated. Acute illnesses, such as the common cold, can sometimes go away on their own.

  • Chronic Diseases

Chronic diseases are illnesses that develop over time and endure for a long time or even a lifetime. Chronic disease is defined as a disease that lasts more than three years. The symptoms are relatively modest at first.
