Which of the following is not a "ghost-town"?

Detailed Solution:

The correct answer is “Charkhari”.

Charkhari is not a "ghost-town". It is a city in the Mahoba district of Uttar Pradesh, India. It is known as the "Kashmir of Bundelkhand" and has a significant population.

The other options - Kuldhara, Dhanushkodi, and Lakhpat - are all considered ghost towns due to various reasons such as abandonment, natural disasters, or historical events.
