Solution.

CBSE answer: (1)

Answer: (1) Showing children the scientific process and the patient effort behind a discovery

  1. The story of Ronald Ross is told so children see how a scientist observes, guesses, tests and keeps trying after failures.
  2. It builds curiosity and respect for the method of science.
  3. Options (2) and (4) are isolated facts, not a learning purpose.

Trap: Option (3) is a fact from the story, and the word 'only' makes it weak as a reason.
