Which order is wingless hexapods with no eyes or antennae and entognathous mouthparts, and is ametabolous?

Explanation:
Protura fit this combination because they are small, wingless hexapods that lack both eyes and antennae, and they have entognathous mouthparts tucked inside the head. Their development is ametabolous, meaning there is no metamorphosis and juveniles resemble adults. While other basal hexapods like Collembola and Diplura also have entognathous mouthparts, they possess antennae (and often eyes), so they don’t match all the traits described. Thysanura have antennae and eyes as well. So Protura is the best match for this description.
