Leave policy India - sent on business travel on weekend and when returning he had a long journey

Hi All, If a person was sent on business travel on weekend and when returning he had a long journey around 20-24 hrs drive arranged by company, and due to long journey if he took off next day will it be considered as CL / Compensatory off? Or it should be considered as Business travel off?

Hi,
It should be considered as compensatory off as he was traveling after his work hours till next working day.
But what is business travel off beyond this I did not understand.
