To arrange the important National Days of India in chronological order, we need to know the specific dates on which each day is celebrated. Here are the relevant details:
- National Youth Day: Celebrated on January 12 to commemorate the birth anniversary of Swami Vivekananda.
- National Teacher's Day: Celebrated on September 5 in honor of Dr. Sarvepalli Radhakrishnan's birthday.
- National Science Day: Celebrated on February 28 to mark the discovery of the Raman Effect by C.V. Raman.
- National Hindi Day: Celebrated on September 14 to honor the adoption of Hindi as one of the official languages of India.
- National Children's Day: Celebrated on November 14 in India to mark the birthday of Jawaharlal Nehru.
We now arrange these days in the order of their occurrence throughout the year:
- National Youth Day: January 12
- National Science Day: February 28
- National Teacher's Day: September 5
- National Hindi Day: September 14
- National Children's Day: November 14
Thus, the correct chronological sequence is: (C) National Youth Day, (B) National Teacher's Day, (A) National Science Day, (Ε) National Children's Day, and (D) National Hindi Day, which matches the option:
(C), (B), (A), (Ε), (D)
