Which consequence occurs when the prothoracic gland atrophies prematurely in a beetle larva?

💡 Explanation

Premature gland atrophy prevents ecdysone release; thus, larval molting arrests because the hormonal trigger is absent. Without sustained ecdysone, the larva cannot attain pupation, therefore correct rather than prematurely metamorphosizing or wrongly differentitiating, needing ecdysone.
