Which outcome arises when the prothoracic gland atrophies during insect metamorphosis?

💡 Explanation

Premature atrophy prevents ecdysone production, a key molting hormone; this arrests the normal progression through developmental stages because the pupal or adult stage cannot be initiated, therefore development ceases, rather than progressing or uncontrollably continuing larval stages.
