At what age did Sansar Chand ascend to the throne?

10 years

The correct answer is Option 4- 10 years

Sansar Chand ascended to the throne at the tender age of 10 years after the kingdom had been restored to its earlier glory by his grandfather Ghamand Chand. They belonged to the Katoch dynasty of rulers, who had been ruling the Kangra region for a long time until Jahangir conquered their territory in the seventeenth century and made them his vassals. After the decline of the Mughal power, Raja Ghamand Chand recovered most of the territory and founded his capital town of Tira Sujanpur on the banks of river Beas and constructed fine monuments. He also maintained an atelier of artists.
