Explanation: UNESCO World Heritage Sites are globally recognized places of outstanding cultural or natural importance. India, with its rich cultural heritage and diverse natural landscapes, has a significant number of these sites. As of the latest data, India has more than 40 UNESCO World Heritage Sites, which include both cultural and natural sites.
The Jaipur City, also known as the Pink City, was recently added to the UNESCO World Heritage Sites list under the cultural category. This addition highlights the city's architectural and historical significance, particularly the urban planning and architectural styles that reflect the cultural and artistic achievements of the 18th century.
Kaziranga National Park, located in Assam, is a natural site known for its conservation efforts and the protection of the one-horned rhinoceros. It is not classified as a 'Mixed Category' site. The 'Mixed Category' designation is given to sites that have both cultural and natural significance, but Kaziranga is recognized solely for its natural heritage.
The confusion might arise from the fact that some sites in India, such as the Western Ghats, are classified as 'Mixed Category' sites. However, Kaziranga National Park is not one of them. It is a natural site that showcases the biodiversity and conservation efforts in the region.
In summary, the correct statement is that Jaipur City was the latest addition to the UNESCO World Heritage Sites list under the cultural category. The other statements about the number of sites and the category of Kaziranga National Park are not accurate. Understanding the specific categories and the criteria for UNESCO World Heritage Sites is crucial for correctly identifying and appreciating the significance of these sites in India and around the world.
