Q4 Read the passage given below and write the option that you consider the most appropriate in your

THE DISGUISE ARTISTS
Aesop prawns start life as colourless, almost transparent infants who drift with the tide. On reaching
maturity, they drift inshore, reach out to grasp the first passing seaweed and, once established upon
it, they proceed to colour themselves to blend with it. After a week, their colouring is complete and
they are safe from the closest scrutiny. Should disaster strike and their chosen home be destroyed,
they first try to find a new home with the same colour scheme as the first. If this proves impossible,
they philosophically settle for a different coloured home and restart their own colouring process. A
week zips past --- and they change colour to merge beautifully with their new homes once again.
Aesop prawns also take on the colours of the day. Regularly at nightfall, they change to a deep
transparent blue, reverting to their chosen house-colour as the sea lightens at dawn. Interestingly, the
"decision" to adopt a particular colour is in no way an act of will on the part of the prawn. Scattered
over its body surface are small pigment cells, each containing a central bag of colours (a reservoir of
primary pigments: red, yellow and blue) with five branches extending from it. These pigment cells are
influenced by the light that falls directly on them or enters through the prawn's eyes. Different
coloured lights activate the hormones that control the flow of pigments. And after dark, red and
yellow are withdrawn to make way for the nocturnal blue 'night suit' of the Aesop prawn. A system
that provides the animal, at all times, with an enviable cloak of invisibility
