The question asks to identify a multicellular organism that commonly reproduces through fragmentation, a type of asexual reproduction.

Fragmentation Explained

Fragmentation is a mode of asexual reproduction where an organism breaks into several pieces (fragments), and each fragment grows into a new, independent organism. This is common in simple multicellular organisms.

Analyzing the Options

• Spirogyra: This is a type of green alga. It is multicellular and commonly reproduces by fragmentation. When the filamentous structure breaks, each part can regenerate into a new filament.
• Bryophyllum: This plant reproduces vegetatively through buds that form on the margins of its leaves, not typically by fragmentation of the main plant body.
• Orange: This is a multicellular plant. While it can be propagated asexually through methods like grafting, its natural reproduction is primarily sexual (via seeds), and fragmentation is not its common mode.
• Jasmine: Similar to Orange, Jasmine is a plant that reproduces sexually through seeds. Asexual propagation is done through cuttings, not fragmentation.

Conclusion on Fragmentation

Among the given options, Spirogyra is the multicellular organism that clearly exhibits fragmentation as a common method of asexual reproduction.
