Solution
The correct option is B Weismann
The inheritance of acquired characteristics is a hypothesis that physiological changes acquired over the life of an organism (such as the enlargement of a muscle through repeated use) may be transmitted to offspring. The basic concept of inheritance of acquired characters was finally widely rejected in the early 20th century. It was disapproved by experiment conducted by Weismann. Weismann conducted the experiment of removing the tails of 68 white mice, repeatedly over 5 generations and reporting that no mice were born in consequence without a tail or even with a shorter tail. Therefore, the correct answer is option B.
