Which outcome prevents complete metamorphosis during pupal ecdysis?

💡 Explanation

Disrupted ecdysone receptor activation leads to failed pupal-to-adult transition because it governs molting and differentiation. The mechanism involves nuclear receptor signaling; therefore, the insect remains partially pupal rather than achieving full metamorphosis.
