Explanation
The correct answer is Option 4 i.e. 1975.
Sikkim became the 22nd state of India in the year 1975. Earlier, it was a protectorate under India, with its own monarchy. Growing political unrest and demands for democratic reforms led to a referendum in April 1975, where the majority of Sikkimese people voted to abolish the monarchy and join India. Following this, the Indian Parliament passed the 36th Constitutional Amendment, making Sikkim a full-fledged state. This marked a significant shift in the region's political status and integrated Sikkim into the Indian Union officially on May 16, 1975.
