Explanation:

Gupta (Correct): The Gupta period (c. 320–550 CE) is often referred to as the "Golden Age of India" and is renowned for its extensive issuance of gold coins. These coins, known as 'dinars', were of high purity and artistic excellence, depicting various deities, kings, and scenes, reflecting the prosperity and cultural zenith of the empire. The sheer volume and variety of gold coins from this era are unparalleled. Kushan: The Kushan Empire (c. 1st–3rd century CE) was one of the first to issue many gold coins, but the quantity and artistic diversity were surpassed by the Guptas. Maurya: The Mauryan Empire (c. 322–185 BCE) primarily used punch-marked silver and copper coins; gold coins were rare. Hind Yawan (Indo-Greek): These kingdoms (c. 2nd century BCE–1st century CE) issued sophisticated coinage, including some gold, but their output was limited compared to the Gupta Empire.
