Correct Answer - Option 1 : Jhalrapatan
1) Jhalrapatan → Jhalrapatan is a town in Jhalawar district in the south of Rajasthan state in India.
2) Ahmedabad → Ahmedabad, in western India, is the largest city in the state of Gujarat.
3) Rajkot → Rajkot is a city in the western Indian state of Gujarat.
4) Surat → Surat is a large city beside the Tapi River in the West Indian state of Gujarat.
All options except ‘1’ are cities located in Gujarat while Jhalrapatan is a town in Rajasthan.
Hence, ‘Jhalrapatan’ is the odd one out.
