Question

where are you going rohan change into indirect speech​

Answer 1

By changing the speech we will get this..
''He asked Rohan that why had he come back''?
Indirect speech: In this, we convey the speaker's message in our own words.
It is indirectly conveyed by someone else.
Direct speech: In this situation, the speaker quotes his own words without any change.
These are the actual words without phrasing it into other words.
