The correct answer is C. 1398 AD.
Timur, also known as Tamerlane, was a 14th-century Turco-Mongol conqueror who founded the Timurid Empire. He was a skilled military strategist and tactician, and he led a series of successful campaigns that conquered much of Central Asia, the Middle East, and India.
In 1398, Timur invaded India and sacked the city of Delhi. He then turned his attention to the city of Nagarkot (Kangra), which was located in the foothills of the Himalayas. Nagarkot was a well-fortified city, but Timur’s forces were able to breach the walls and capture the city.
The sack of Nagarkot was a devastating blow to the city. Many of the inhabitants were killed, and the city was left in ruins. Timur’s invasion of India marked the beginning of a period of decline for the Delhi Sultanate.
Option A is incorrect because it is the year that Timur invaded Delhi. Option B is incorrect because it is the year that Timur was born. Option D is incorrect because it is the year that Timur died.
