Solution

The correct option is B Pander
a) Hans Spemann (1869-1941), a German embryologist, discovered the embryonic induction effect. He got a Nobel prize in Physiology or Medicine for his discovery in 1935.
b) Heinz Christian Pander (1794-1865), a baltic German biologist and embryologist, is known as the father of embryology. He is known for his discovery and explanation of the origin and structure of the three germ layers of the chick embryo, which he called as chick blastoderm. He observed that the germ layers further develop into different organs of the body.
c) Charles Bonnet (1720-1793), a Genevan biologist discovered parthenogenesis i.e. reproduction without fertilisation.
So, the correct answer is option B.
