A. I-A, II-B, III-C, IV-D
B. I-D, II-B, III-C, IV-A
C. I-B, II-A, II-D, IV-C
D. I-D, II-A, III-C, IV-B

Answer 1

Hint: in given match the following column I represents the evolution theory while column II represents the scientist who represents it, evolution is the variations inheritable characteristics of the particular biological population over successive generations.

Step by step answer:I. Modified form of Lamarckism:- the Neo-Lamarckism is also known as Lamarckism inheritance, it denotes that the parent organisms use or disuse of physical character during its lifetime can pass on to their offspring. It is also called soft inheritance.
II. Variation and evolution in plants:- it is a book that was written by G. Ledyard Stebbins In 1950, which gives the modern synthesis of evolution and genetics, the significance of this book is that it effectively crushed any serious belief in the alternative mechanism of evolution for plants, like a soft inheritance.
III. Germinal selection theory:- The August Weismann gives the Germ Plasm theory, which states that the inheritance is only possible employing the germ cell (sperm and egg cells), other cells of the body function as somatic cells they do not function as hereditary material.
IV. Supporter of Lamarck's theory:- Etienne Geoffroy is the supporter of Lamarck theory of evolution and he is a colleague of Jean-Baptiste Lamarck, he established the principle of unity of composition.

Hence, the correct option is C.

Note: The most widely accepted theory of evolution is given by Charles Darwin and Alfred Russel Wallace evolution by natural selection, in the 19th century in Darwin’s book “On the origin of species”. In the 20th century, another competitive idea prevailed for evolution like mutation and orthogenesis, which refused and reconciled Darwinian evolution with classical genetics .
