12000, 10000

The correct answer is Option 3- 12000, 10000

The duration of the Mesolithic period is from about 12000 years ago to 10000 years ago.

The Mesolithic period, also known as the Middle Stone Age, is the period in human history between the Paleolithic period and the Neolithic period. It is characterized by the development of smaller and more sophisticated stone tools, as well as the beginning of farming and domestication of animals.

The Mesolithic period began at the end of the last ice age, when the climate began to warm and the glaciers retreated. This change in climate led to changes in the environment, which in turn led to changes in the way that people lived.

During the Mesolithic period, people began to live in smaller groups and to move around more frequently. This was because the food supply was more dispersed than it had been during the Paleolithic period. People also began to develop new ways of hunting and fishing, and they began to domesticate animals such as sheep and goats.

The Mesolithic period ended with the beginning of the Neolithic period, which is characterized by the development of agriculture and pottery.
