Solution

The correct option is C Nauplius
When the eggs hatches, the larvae is produced. The larvae may pass through various stages and are known by different names to form an adult. In the case of crustaceans, there are larval and immature stages. This are the stages through which the organism passes during their life cycle and development from the egg stage to adult. Nauplius is the larval stages. This is the larval stage which is found in most of the crustaceans. The nauplius stage is characterized by the use of appendages of the head for swimming. The nauplius is the stage at which a simple, unpaired eye first appears.
Thus, the correct answer is option C.
