Show answer & explanation

Correct answer: C

Concept: In a coding-decoding substitution question, every stated rule ('X is called Y') renames a real-world term without changing the real fact it describes. To find an item's code-name, first identify its actual real-world attribute, then look up that exact term inside the given chain of renames — never work in the reverse direction and never continue past the term you need.

Application: The question gives a chain of renamings:

Real term

Is called

air

green

green

red

red

sea

sea

blue

blue

water

water

pink

Grass's real-world color is green (a fact independent of the code). Looking up 'green' in the chain shows it is called 'red'. So, under this code, the color of grass is termed red.

Cross-check: Reversing the lookup confirms it: only 'green' is renamed to 'red' in the chain — no other real term maps to 'red' — so 'red' is the unique, correctly-directed answer for grass's real color.
