The correct answer is: C. 2300 BC
Mohenjo-daro is an archaeological site in the Indus Valley Civilization located in the Larkana District of Sindh, Pakistan. Built around 2600 BCE, it was one of the largest settlements of the Indus Valley Civilization, and one of the world’s earliest major urban settlements, contemporaneous with the civilizations of ancient Egypt, Mesopotamia, and Crete.
The site was abandoned in the 19th century BCE, and was not rediscovered until 1922. Excavations have revealed a well-planned city with a grid pattern of streets, public buildings, and houses. The city was also home to a number of large public baths, which are some of the earliest known examples of public sanitation.
Mohenjo-daro is a UNESCO World Heritage Site, and is considered to be one of the most important archaeological sites in the world.
Option A: 2500 BC is too early. The Indus Valley Civilization is thought to have emerged around 2600 BCE.
Option B: 2500-2000 BC is too broad. The Indus Valley Civilization lasted for over 1000 years, so it is impossible to say exactly when Mohenjo-daro was built within this time period.
Option C: 2300 BC is the correct answer. Mohenjo-daro is thought to have been built around 2300 BCE.
Option D: 2200 BC is too late. The Indus Valley Civilization began to decline around 1900 BCE, so it is unlikely that Mohenjo-daro was built after this time.
