Answer 2

Darwin’s natural selection theory:

• Option “A” is correct i.e. discontinuous variation.

• Darwin in his natural selection theory did not believe in any role of discontinuous variation.

• Darwin in his 'natural selection theory' did not consider any role of discontinuous variation in organic evolution. Rendering to this theory, organic evolution is a continuous process.
