• A. A, E, B, D, C
• B. B, C, A, D, E
• C. C, E, A, D, B
• D. E, D, B, A, C

Hint:

Lac insect life cycle starts with egg, followed by nymph, lac secretion, covering of twigs, and fertilization.

Answer 1

The Correct Option is C

Concept:
Lac insect produces lac resin. Its life cycle includes egg, nymph, settlement, secretion of lac, covering of twigs, and fertilization.

Step 1: Egg.
The life cycle begins with eggs. \[ \text{First step}=C \]

Step 2: Nymph.
Eggs hatch into nymphs, which move and settle on host twigs. \[ \text{Second step}=E \]

Step 3: Lac secretion.
After settling, nymphs start secreting lac resin. \[ \text{Third step}=A \]

Step 4: Covering of twigs.
The secreted lac forms a covering on twigs. \[ \text{Fourth step}=D \]

Step 5: Male fertilizes the female.
Later, male fertilizes the female and the cycle continues. \[ \text{Fifth step}=B \] Thus, the correct sequence is: \[ C,E,A,D,B \] \[ \therefore \text{Correct Answer is (C)} \]
