Which developmental outcome occurs when larva experiences premature ecdysone exposure across multiple stadia?

A)Accelerated molting into smaller pupae
B)Complete metamorphosis with missing appendages
C)Disrupted segment identity development
D)Amplified adult size from increased growth

💡 Explanation

When premature ecdysone exposure occurs, precocious activation of molting receptors induces molting because hormone triggers cascade regulating gene expression, results in earlier than normal transformations ending in reduced size pupae. Therefore pupae development results, rather than appendage loss, segment disruption, or amplification requiring altered gene gradients.
