Which one of the following item was collected only in cash under the Mauryas?

During the Mauryan Empire, various forms of revenue and taxes were collected by the state to support its administration and activities. Among these revenue items, "Hiranya" refers to gold and precious metals, which were collected only in cash.

The Mauryan administration collected revenue through various means, including taxes on land, agriculture, trade, and other economic activities. The revenue collected from these sources was used to fund the empire's infrastructure, military, and other administrative expenses.

Option A: Kara, Option B: Bhaga, and Option C: Pranaya were not specifically associated with the collection of revenue only in cash. These terms might refer to different types of taxes, shares, or contributions collected by the Mauryan administration.

Therefore, the correct answer is Option D: Hiranya, as it represents an item that was collected only in cash under the Mauryan Empire.
