Final answer:
Both termite larvae and ant larvae are legless during their larval stage. Both go through metamorphosis where they will develop the adult features including legs for their species, but as larvae, neither have legs. Therefore, the correct answer is option c. both are true.
Step-by-step explanation:
The question asks which of the following are legless: termite larvae or ant larvae. The correct answer to this question is that both termite larvae and ant larvae are legless. In their larval stage, these insects have not yet developed their adult appendages, which includes legs. So, option c. both are true is the correct answer.
Termite larvae and ant larvae are both examples of arthropods at an immature stage. Unlike myriapods, such as centipedes and millipedes, which are known for having numerous legs, the larvae of many insects, including termites and ants, do not possess legs. As they mature, they will go through metamorphosis and emerge as adults with the characteristic features of their species, such as the jointed legs seen in adult ants.
