Detailed Solution

(A) is correct. Paurometabolous development is a type of incomplete metamorphosis, characterised by gradual changes from nymphal stages to adults without a distinct pupal stage. In paurometabolous insects like cockroaches, the nymphs resemble miniature adults and undergo a series of molts until reaching the adult form.

(R) is false. The next to last nymphal stage has wing pads but only adult cockroaches have wings. The nymphs gradually develop wing pads during successive molts. The final molt results in the emergence of fully formed wings in the adult stage.
