a) The domestication of animals
b) The invention of bows and arrows
c) The development of agriculture
d) The use of pottery
The correct answer is c) The development of agriculture.
Agriculture was not a significant development during the Mesolithic Era. It was during the Neolithic Era that agriculture began to develop. The Mesolithic Era was a transitional period between the Paleolithic and Neolithic Eras, characterized by the development of new hunting and gathering techniques, the use of bows and arrows, and the domestication of animals.
