Which outcome occurs when juvenile hormone (JH) concentration is moderately sustained during activation of imaginal discs?

A)Complete pupation does not occur
B)Larval molting cycles continue normally
C)Adult structures fully differentiate
D)Uncontrolled cell proliferation is triggered

💡 Explanation

A sustained moderate JH level allows some development; however, complete development to pupation does not occur because gene expression isn't fully switched on. This prevents the transition into the pupa stage, rather than normal molting; therefore, outcome A. Full differentiation requires lower JH.
