Solution

The correct option is A Weismann
Weismann conducted an experiment of removing the tails of 68 white mice over 5 generations. After 5 generations, he reported that no mice were born in consequence without a tail or even a shorter tail. This experiment disapproved the concept of acquired characters, a theory given by Charles Darwin.
So, the correct option is 'Weismann'.
