Option 1 -> Kushanas ruled from 1st-3rd century CE and introduced large-scale gold coinage in India during this period.
Option 2 -> Mauryas (322-185 BCE) primarily used punch-marked silver coins, predating the First Century CE timeframe.
Option 3 -> Guptas (320-550 CE) were famous for gold dinars but came later, in the 4th century CE onwards.
Option 4 -> Chalukyas emerged much later, around the 6th century CE.
Hence, Kushanas -> They were the first dynasty to issue gold coins on a large scale in India around the First Century CE, particularly under rulers like Vima Kadphises and Kanishka, introducing Roman-influenced gold coinage to the subcontinent -> correct
