The Correct Option is B

Solution and Explanation

Gregor Johann Mendel $(1822-84)$ is known as Father of Genetics. Mendel's work remained un-noticed and unappreciated for some $34$ years. In $1900$, three workers independently rediscovered the principles of heredity already worked out by Mendel. They were Hugo de Vries of Holland, Carl Correns of Germany and Erich von Tschermak of Austria.

Mechanisms of Evolution

The mechanism of evolution has been explained with theories such as the Big Bang Theory, the Theory of Darwin, and the Hardy-Weinberg Equilibrium where evolution is the process of natural selection that causes changes in the traits of species over multiple generations. 

The Big Bang Theory:

The most widely accepted theory for the origin of life on Earth and its various forms is the Big Bang Theory. According to the hypothesis, as a result of a massive explosion, the universe was created 20 billion years ago.

Hardy-Weinberg Equilibrium:

According to the idea of Hardy-Weinberg, allelic frequency and gene pool remain stable throughout generations. Furthermore, the allelic frequencies add up to 1.

Theory of Darwin:

The Theory of Darwin's natural selection hypothesis provided a more reasonable explanation for the emergence of new species. As a result of adaptation to changing environmental conditions, natural selection led to the evolution of multiple species from a single species.
