The correct answer is option 3, which means that wetlands are present in Keoladeo Ghana National Park and Sultanpur National Park.

Keoladeo Ghana National Park, also known as Bharatpur Bird Sanctuary, is a wetland located in Rajasthan, India. It is home to a diverse range of bird species and has been recognized as a Ramsar site, indicating its international importance as a wetland.

Sultanpur National Park, located in Haryana, India, is also a wetland area. It was initially declared as a bird sanctuary to protect the bird population, and later it was upgraded to a national park.

Mudumalai Wildlife Sanctuary, on the other hand, is not a wetland. It is a protected area in Tamil Nadu, India, known for its rich biodiversity and diverse range of flora and fauna.

In summary, out of the three options given, Keoladeo Ghana National Park and Sultanpur National Park are wetlands, while Mudumalai Wildlife Sanctuary is not.
