The correct answer is (d).
The President of India, Pranab Mukherjee, addressed the Vidhan Sabha of Uttarakhand for the first time on 21 May 2015. This was the first time that a President had addressed the Vidhan Sabha of any state in the Hindi-speaking belt.
The President’s address was significant for a number of reasons. First, it was a sign of the growing importance of Uttarakhand in the national political landscape. Second, it was a recognition of the state’s unique challenges and opportunities. Third, it was an opportunity for the President to connect with the people of Uttarakhand and to share his vision for the state’s future.
The President’s address was well-received by the people of Uttarakhand. They appreciated the President’s recognition of the state’s importance and his commitment to its development. They also welcomed the President’s call for unity and harmony in the state.
The President’s address was a major boost for the state of Uttarakhand. It helped to raise the state’s profile and to attract investment. It also helped to build a sense of pride and unity among the people of Uttarakhand.
The other options are incorrect because the President of India did not address the Vidhan Sabha of those states in May 2015.
