B) (ii) and (iii)
C) (iii) and (iv)      
D) (i), (ii) and (iii)

Answer 1

Hint The ability of plant cells to regenerate into a complete plant is called the regeneration process. It is a natural process of replacing or restoring damaged or missing cells, tissues, organs, and even entire body parts to full function in plants and animals.

Complete Step-by-step answer:

Bee-keeping or apiculture is the maintenance of hives of honeybees for the production of honey. Honey has high nutritive value and also is used in the indigenous systems of medicine. Bee-keeping should be carried out in an area where there are plenty of bee pastures of some shrubs, fruit orchards, and cultivated crops. Animal husbandry is an agricultural practice. It includes breeding and raising livestock. This skill is very important to farmers and is as much science as it is art. Animal husbandry includes taking care and breeding of livestock like buffaloes, cows, pigs, etc.
A breed is a group of animals that are almost identical in most characteristics like general appearance, features, size, configuration, etc. When breeding is between animals of the same breed it is called inbreeding. The crosses between different breeds are called outbreeding. 
Somaclonal variation: plants derived from tissue culture have been variously referred to as somaclones or calciclones or protoclones and the genetic and epigenetic variations displayed by such plants are simply called somaclonal variations. 
Hence the correct answer is option D.
Note: Larkin and Scowcroft (1981) used this term to describe the genetic variability among plants derived from tissue culture. Similarly, gametoclonal variations describe variations in clones that are raised from gametic or gametophytic cells.
