The correct option is A Not everyone could read Sanskrit in those days so the only way for them to enjoy the epics, the Puranas, and folk tales was to listen to Harikathas
Harikathas were usually stories of gods and saints from epics and puranas related to them. The epics were in Sanskrit and so not everyone was able to read those stories. The Harikathas were songs people could listen to. This made them popular among the masses.
