Solution
The correct option is C Evening primrose
Hugo de Vries studied the inheritance of flower colour in Evening Primrose and proposed mutation theory that says that mutations are sudden, random, inheritable and discontinuous variations which serve as raw material for evolution. But the observed mutations were actually chromosomal aberrations. Punnett conducted hybridization experiments on sweet pea plant just like those of Mendel on garden pea plant. H. B. D. Kettlewell studied the evolution of a dark coloured variety of moth (Biston bitularia carbonaria) due to industrial pollution and called it as industrial melanism. So, the correct answer is option B.
