The correct option is option B- Alfred Russel Wallace.

Explanation:

Alfred Russel Wallace was a British naturalist who worked with Darwin and helped him in establishing his theory of natural selection.

Wallace supplied birds to Darwin for his studies and even sent his theory to Darwin in 1858 which almost was the exact copy of the theory of Darwin.

Their relationship is considered one of the most important scientific relationship in the history of science where Wallace supported and admired "On the origin of species" and Darwin appreciated Wallace as the man who truly understood the theory of natural selection.

Thus, option B- Alfred Russel Wallace is the correct answer.
