Which structural adaptation results when juvenile hormone diminishes sharply during pupae formation?

A)Triggered apoptosis of most larval cells
B)Induced secretion of chitinous cuticle
C)Prolonged expression of prothoracicostatic hormone
D)Suppressed segmentation gene transcription permanently

💡 Explanation

Apoptosis occurs because diminished juvenile hormone allows imaginal discs to differentiate via developmental cascade, therefore adult structures form rather than continued larval growth due to halted larval gene expression.
