In animals, an intentional, programmed death of some cells occurs through a process called apoptosis.
<h3>What is
apoptosis?</h3>
Multicellular organisms go through a process called apoptosis, which is a type of programmed cell death. The morphology and death of cells are influenced by biochemical processes. The following modifications occur: chromatin condensation, DNA fragmentation, mRNA decay, nuclear fragmentation, cell shrinkage, and blebbing. The daily loss of cells by the typical adult human due to apoptosis ranges from 50 to 70 billion. Between twenty and thirty billion human cells die every day in children between the ages of eight and fourteen on average.

Answer:
Have larvae which are motile and move via the motion of cilia. (Ans. A)
Explanation:
Sponges: They are belongs to porifera phylum and defined as the simplest species. In sponge for particular function they are containing specialized cells, and they lack true tissues. All sponges are marine or aquatic in nature.
Sponge lives in contact with water because it helps them to excretion, gas exchange, and feeding. They can filter out the food, eliminate waste, and absorb dissolved oxygen with the help of body structure of sponge is dedicated to moving water.
Sponges produce motile larvae through the process of sexual reproduction, and move with the motion of cilia or budding formation through the process of asexual reproduction.
