Complete Answer:
A) Lamarck proposed the theory of “inheritance of acquired characters”.

B) Origin of species published on 20 November, 1859 by Charles Darwin. It is a work of scientific literature which is considered as the base of evolutionary biology.
Darwin proposed that the population evolve over the course of generation by the process of natural selection.
Natural selection is the unequal ability of an individual to reproduce and survive on the basis of suitability of their inherited characteristics to prevailing environmental conditions. Natural selection is the key point or driving force in evolution used to justify certain political, economic or social views.

C) De Vries gave the “mutation theory”.

D) Mendel experiments on the garden pea plant and proposed “Law of inheritance”. ‘Pisum sativum’ is the scientific name of garden pea.

The correct answer is option B i.e., Darwin.

Note: Darwin is considered as the father of evolution. Darwin’s theory is also called Darwinism. There are two main points in the Darwin’s theory:
A) The diverse group of animals evolve from one or few common ancestors.
B) The mechanism by which this proposition takes place is natural selection.
