Answer:
D. Parenchymula
Read Explanation:
The larval stages of sponges include: Planula: A free-swimming, ciliated larval organism that results from multiple cell divisions of a zygote Amphiblastula: A common larval stage found in scypha Parenchymula: A common larval stage found in leucosolenia Sponges have a life cycle that includes a vegetative growth phase, gemmulation (asexual reproduction), sexual reproduction, cryptobiosis (resting phase), gemmule hatching, and regeneration. If sexual reproduction occurs, parenchymella larvae are produced and disperse before developing into a mature sponge.
