Which consequence results when a larval insect's steroid production is impaired during a critical instar?

💡 Explanation

Complete stunting of growth results because the steroid hormone ecdysone triggers molting; therefore, without sufficient ecdysone production, the insect cannot progress to the next instar stage, rather than reaching a pupal stage with imaginal disc development.
