Detailed explanation-1: -Hydras usually reproduce asexually by “budding”-a new hydra starts as a “bud” forming on the side of a hydra’s body; it grows and eventually breaks away as a clone of the original. Some species reproduce sexually, releasing sperm into the water that can reach eggs on another hydra.

Detailed explanation-2: -Organisms such as hydra use regenerative cells for reproduction in the process of budding. In hydra, a bud develops as an outgrowth due to repeated cell division at one specific site. These buds develop into tiny individuals and, when fully mature, detach from the parent body and become new independent individuals.

Detailed explanation-3: -Hydra reproduces by the mechanism of budding and fragmentation. It cannot undergo multiple fission since that is not a viable option for a multicellular organism such as Hydra. Spore formation is an asexual method of reproduction, mostly seen in fungi.

Detailed explanation-4: -In hydra too the new individuals develop as outgrowths from a single parent. This type of reproduction in which only a single parent is involved is called asexual reproduction. Since new individuals develop from the buds in hydra, this type of asexual reproduction is called budding.
