Which amongst the following rulers issued the coin called 'Rupia'?

The correct answer is Option (1) → Sher Shah

Sher Shah Suri, who drove the Mughal emperor Humayun out of India and ruled from 1540 to 1545, introduced a standard silver coin called the ‘rupiya’, weighing about 178 grains. He also issued the copper ‘dam’. The Mughals kept his coinage after Humayun returned, and the name lives on in today’s rupee.
