Statement (II) : Chelicerae are the inner portion of mouth parts of termite soldiers

EXPLANATION
Excretory, Endocrine, Reproductive Physiology
- Arthropod Molting and Mouthpart Anatomy:
- Statement (I) is incorrect: Apolysis is the initial detachment of the epidermal cells from the old cuticle; ecdysis is the subsequent physical shedding and casting off of the old exuviae. They are distinct sequential stages of the molt cycle.
- Statement (II) is incorrect: Chelicerae are the pincer-like or fanged feeding appendages characteristic of chelicerate arthropods (spiders, scorpions, ticks, mites). Termite soldiers belong to the order Blattodea (mandibulate insects) and possess heavily sclerotized, adapted biting mandibles, not chelicerae.
- Conclusion: Both Statement (I) and Statement (II) are incorrect (Option 2).
Correct option: (2) Both Statement (I) and Statement (Il) are incorrect
