Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Planaria, sponges, and starfish reproduce by which method of asexual reproduction?
A
Regeneration
B
Sporulation
C
Vegetative propagation
D
Budding
Explanation: 

Detailed explanation-1: -Starfish reproduces asexually by the process of regeneration. In the process of regeneration, one or more parts of the organism get divided and each divided part develops into a complete organism.

Detailed explanation-2: -Starfish exhibit an asexual mode of reproduction through binary fission and regeneration. Starfish is a bisexual organism and undergoes regeneration as a method for asexual reproduction. In binary fission, the parent organism’s cell divides exactly into two genetically identical daughter cells.

Detailed explanation-3: -Asexual freshwater planarians reproduce by tearing themselves into two pieces by a process called binary fission. The resulting head and tail pieces regenerate within about a week, forming two new worms.

Detailed explanation-4: -starfish follows the fragmentation method.

Detailed explanation-5: -Asexual reproduction in starfish takes place by fission or through autotomy of arms. In fission, the central disc breaks into two pieces and each portion then regenerates the missing parts.
