• A. B, D and E only
• B. A, C and E only
• C. B and D only
• D. E only

Answer 1

The correct option is A B, D and E only

Variation is not the process by which characters are passed on to the progeny but inheritance is the actual process by which the characters are passed from the parent to the progeny. The variation, on the other hand, results in the permanent change in the chemical structure of chromosomes which is caused by a mutation. Also, Inheritance is the process by which genetic information is passed on from parent to child. This is why members of the same family tend to have similar characteristics.

So, the correct option is 'B, D and E only'.
