Answer 1

In ancient times there were many theories regarding the origin of diseases in the human. During that period there are many misconceptions regarding the origin of the diseases.

Complete answer: 1. During ancient times when people did not know the actual reason behind the diseases that occur in humans, they thought that God and any other supernatural power is responsible for the diseases. Such superstitions are very common in society. Then Hippocrates proposed his theory of humor which is based on the production of the black bile pigment.

3. According to the theory of humor, Hippocrates believed that humor is a vital part of our body and all vital fluids like blood, black bile, lymph regulate the normal functions of the body.
4. When we suffer from diseases the body fluids or the humor amount in our body get reduced, so he believes that the cause of the diseases is natural and present inside the body.

So, the correct answer is “Option B ”.

After that Louis Pasteur theory for the cause of diseases was widely accepted all over the world and believed that the diseases were caused by the infections that were carried out by the diseases causing microorganisms.
