The correct answer is option 'A', Rupee, which was not the currency used during the later Vedic age. The later Vedic age refers to the period in ancient Indian history that followed the Early Vedic age and is believed to have lasted from around 1000 BCE to 600 BCE.

During the later Vedic age, the economy was primarily agrarian, and the main occupation of the people was agriculture. Trade and commerce also started to develop during this period. However, there is no historical evidence to suggest that the rupee was used as a currency during this time.

The currency used during the later Vedic age was mainly in the form of metals such as gold, silver, and copper. The most commonly used currency was the Nishka, which was a silver coin. It was used for trade and commerce and had a standardized weight of around 96 grains. The Nishka coins were often imprinted with various symbols and marks to indicate their authenticity.

Another currency used during this period was the Krishnala, which was a gold coin. It had a standardized weight of around 96 grains and was also used for trade and commerce. The Satamana, which was a copper coin, was also used as a currency during the later Vedic age. It had a standardized weight of around 144 grains.

In addition to these metallic currencies, barter and exchange of goods were also prevalent during this time. Agricultural produce, such as grains and livestock, were often used as a medium of exchange.

In conclusion, the rupee was not the currency used during the later Vedic age. The main currencies during this period were the Nishka (silver coin), Krishnala (gold coin), and Satamana (copper coin), along with the practice of barter and exchange of goods.
