Asexual reproduction in starfish occurs through
A
budding and binary fission
B
fragmentation and budding
C
regeneration and binary fission
D
fragmentation and regeneration
Explanation: 

Detailed explanation-1: -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.

Detailed explanation-2: -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-3: -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.

Detailed explanation-4: -Asexual reproduction amongst starfish is through fission where the starfish’s central disc is split into two pieces or autotomy where one or more of the starfish’s arms are lost. Some starfish can regenerate from just a fragment of one arm. A single arm which has become separated from its host is known as a comet.

Detailed explanation-5: -2) In fragmentation, reproduction occurs via the breakage of the parent organism into various fragments that have the ability to grow identical to their parents. It is commonly found in coral, sponges, and starfishes.
