Solution

The correct option is B Clone
A) Callus is unorganized actively dividing the mass of cells maintained in culture. It has a meristematic cell which has ample amount of cytoplasm to trigger cell division. It is treated with the growth hormones to allow the cell division and differentiation.
B) A population of genetically identical individuals, obtained from asexual reproduction is a clone because fusion of gametes does not take place in vegetative propagation so there is no chance of recombination and variation. The parent cell divides to form daughter cell by mitosis due to which the offspring are genetically identical to the parent. The offspring produced are clones of their parent and have the same number of chromosomes.
C) Deme is the basic unit of an animal population can interbreed among themselves. It consists of two or more subspecies which can interbreed amongst itself. It shares its own distinct genetic pool. In isolation, the demes turn into distinct species or subspecies.
D) Aggregate is form or group into a class or cluster.
So, the correct answer is option B.
