Solution

The correct option is D Both b and c
Hydra can reproduce by both budding and fragmentation. In Hydra, an outgrowth develops due to repeated cell division at one specific site on the parent body. This outgrowth is called a bud. These buds grow and develop into tiny individuals. When the bud gets fully mature it detaches from the parent body and becomes new independent individuals.

In fragmentation the body of the Hydra breaks into distinct pieces called fragments. Each fragment grows into an adult Hydra which is capable of producing offspring.

Binary fission is also a type of asexual reproduction. In binary fission a parent cell divides into two halves and each rapidly grows into an adult. Example: Amoeba, Paramecium.
