a	Paurometabolous	Silk worm
b	Hemimetabolous	Grasshopper
c	Holometabolous	Silver fish
d	Ametabolous	Dragon fly

• A. a(ii), b(iv), c(i), d(iii)
• B. a(i) , b(iii) , c(iv) , d(ii)
• C. a(ii), b(iii) , c(i) , d(iv)
• D. a(ii) , b(iv) , c(iii) , d(i)

Answer 1

Answer: (A)

a(ii), b(iv), c(i), d(iii)

a) Paurometabolous metamorphosis is characterized by gradual development from the immature stage i.e nymph to the adult stage. Eg- grasshopper.

b) Hemimetabolous metamorphosis is known as incomplete metamorphosis as consists of three stages of development- egg, nymph and adult stage and does not have the pupal stage. Eg- the dragonfly.

c) Holometabolous metamorphosis is called complete metamorphosis as it consists of all the four stages of development- egg, nymph, pupa and adult stages. Eg- silkworm.

d) Ametabolous development refers to the developmental process in which the immature stages are very similar to the adults and no metamorphosis occurs. Eg- silverfish.

So, the correct answer is 'a(ii), b(iv), c(i), d(iii)'.
