Explanation:

Bhutan’s King Jigme Khesar Namgyel Wangchuck was the Chief Guest at the 64th Republic Day Celebrations, becoming the third emperor from the tiny kingdom to grace the event, signifying the importance that India attaches to its neighbour. The Oxford-educated 32-year-old Wangchuck and Queen Jetsun Pema, who did her schooling in Himachal Pradesh, are visiting India for the second time in the past two years. The young king, who is known for inviting his subjects for tea at his palace in the picturesque Bhutanese capital of Thimphu, shares the honour of being the Chief Guest with his father Jigme Singye Wangchuck and grandfather Jigme Dorji Wangchuck.
