The correct option is D All of the above
The Mesolithic Age was a transitional phase between the Paleolithic Age and the Neolithic Age. It had the characteristics of both the Paleolithic Age and the Neolithic Age. The people of this age lived on hunting, fishing, and food gathering while at a later stage they also domesticated animals. The bow and arrow, invented either late in the Paleolithic period or in the Mesolithic period, served hunters and fighters until the firearm took its place. Probably during Mesolithic times, wild dogs, such as jackals, attached themselves to human settlements.
