The correct answer is: a) Dholavira
Dholavira is a Harappan archaeological site located in Kutch district of Gujarat, India. It is one of the largest Harappan sites in India, and is known for its well-preserved fortifications, water management system, and urban planning. The site was excavated by the Archaeological Survey of India from 1989 to 1995.
Dholavira was occupied from the late Harappan period (2600-1900 BCE) to the early Historic period (1900-1300 BCE). The site was abandoned around 1300 BCE, and was not reoccupied until the 19th century CE.
The site is divided into three main areas: the citadel, the lower town, and the cemetery. The citadel is the most impressive part of the site, and is surrounded by a massive fortification wall. The lower town is located to the south of the citadel, and is home to a number of residential and public buildings. The cemetery is located to the east of the citadel, and contains a number of graves.
Dholavira is a significant site for the study of the Harappan civilization. The site provides valuable insights into the urban planning, water management, and social structure of the Harappans.

- b) Rojadi is a Middle Paleolithic site located in Gujarat, India. However, it is not as significant as Dholavira.
- c) Bhimbetka is a rock shelter complex located in Madhya Pradesh, India. It is a UNESCO World Heritage Site, and is known for its prehistoric cave paintings. However, it is not a Middle Paleolithic site.
- d) Lothal is a Harappan archaeological site located in Gujarat, India. It is known for its well-preserved dock and warehouse complex. However, it is not a Middle Paleolithic site.
