The correct option is B

(i) b ,(ii) a, (iii) d, (iv) c

There are many modes of asexual reproduction such as binary fission, budding, fragmentation, etc. In binary fission, first the genetic material is replicated and then the cells divide into nearly two equal daughter cells. Budding on the other hand follows a similar pattern as binary fission; the differing character is that of the daughter cell being smaller than the parent cell. In the process of fragmentation, a split fragment or part of an organism develops into a fully mature individual. Reproduction by fragmentation is seen in starfish, plants like liverworts, etc.

On the other hand, sexual reproduction involves the fusion of male and female gametes produced by two different individuals or parents. The fusion of gametes results in a zygote which develops into a new individual.
