Which disruption during a butterfly pupa's histolysis stage results in incomplete metamorphosis?

A)Premature activation of apoptosis cascades
B)Insufficient degradation of larval tissues
C)Overproduction of juvenile hormone analogs
D)Disabled ecdysone receptor transcription

💡 Explanation

When histolysis malfunctions during the pupa stage, larval tissues may not be sufficiently degraded via programmed cell death because lysosomal enzymes require precise hormonal signaling to break down the larval structures according to the developmental timeline of metamorphosis. Insufficient degradation leads to incomplete, unspecialized development, rather than activation, hormone malfunction or transcriptional inhibition which would result in alternate malformations.
