Evidence suggests that Northeast India, including the area of Mizoram, was likely inhabited by humans during the:

Paleolithic (Old Stone Age) period
Mesolithic (Middle Stone Age) period
Neolithic (New Stone Age) period
All of the above

The correct answer is: d) All of the above

Evidence suggests that Northeast India, including the area of Mizoram, was likely inhabited by humans during the Paleolithic (Old Stone Age) period, the Mesolithic (Middle Stone Age) period, and the Neolithic (New Stone Age) period.

The Paleolithic period is the earliest period of human history, lasting from about 2.5 million years ago to about 10,000 years ago. During this time, humans were hunter-gatherers who lived in small groups. They used stone tools and weapons, and they lived in caves or simple shelters.

The Mesolithic period is the period of human history that lasted from about 10,000 years ago to about 5,000 years ago. During this time, humans began to develop agriculture and to live in larger groups. They also began to make more sophisticated tools and weapons.

The Neolithic period is the period of human history that lasted from about 5,000 years ago to about 3,000 years ago. During this time, humans developed advanced agriculture and began to live in cities. They also began to make pottery and other objects from clay.

There is evidence of human habitation in Northeast India dating back to the Paleolithic period. In 2014, archaeologists discovered a stone tool site in the state of Mizoram that is believed to be about 1.2 million years old. This is the oldest evidence of human habitation in India.

There is also evidence of human habitation in Northeast India dating back to the Mesolithic period. In 2016, archaeologists discovered a cave site in the state of Meghalaya that is believed to be about 8,000 years old. This site contains evidence of human habitation, including stone tools, pottery, and animal bones.

There is also evidence of human habitation in Northeast India dating back to the Neolithic period. In 2017, archaeologists discovered a village site in the state of Assam that is believed to be about 5,000 years old. This site contains evidence of human habitation, including pottery, stone tools, and rice husks.

The evidence suggests that Northeast India, including the area of Mizoram, was likely inhabited by humans during the Paleolithic (Old Stone Age) period, the Mesolithic (Middle Stone Age) period, and the Neolithic (New Stone Age) period.
