Answer

D

Explanation

Lamarckian theory of inheritance of acquired characters was discarded by Weismann, while experimenting on mice. He cut the tails of mice for 80 generations but no single mouse was born without tail. Weismann formulated his famous 'Theory of continuity of germplasm', according to which only those characters, whatever be their origin and nature, that could affect germplasm are heritable and others are not.
