The Salar Jung Museum, known for its vast collection of artifacts, is located in:

Hyderabad
Warangal
Karimnagar
Nizamabad

The correct answer is A) Hyderabad.

The Salar Jung Museum is a museum located in the city of Hyderabad, Telangana, India. It is one of the largest museums in India and houses a collection of over 40,000 artifacts from around the world. The museum was founded in 1914 by Mir Yusuf Ali Khan Salar Jung III, the sixth Prime Minister of Hyderabad State.

The museum is divided into 14 galleries, each of which houses a different collection of artifacts. The galleries include the Arms and Armour Gallery, the Decorative Arts Gallery, the Manuscripts Gallery, the Miniature Paintings Gallery, the Numismatics Gallery, and the Textiles Gallery.

The Salar Jung Museum is a popular tourist destination and is open to the public from 9:30 am to 5:00 pm on all days except Friday. Admission is free for Indian citizens and Rs. 200 for foreign nationals.

The other options are incorrect because they are not cities in Telangana where the Salar Jung Museum is located.
