Which developmental failure occurs when damage impairs histoblast function in a dipteran larva?

A)Retention of larval features persists
B)Complete failure to form a puparium
C)Premature eclosion from the puparium
D)Malformed wings emerge in the adult

💡 Explanation

When histoblast function is impaired, the programmed cell death and replacement of larval cells during metamorphosis is incomplete because histoblasts mediate tissue remodeling. Therefore, larval features persist, rather than puparium failure, premature eclosion, or improperly formed wings, all of which involve separate pathways
