Correct option is C
Let's analyze the given words: Jaipur, Tinsukia, Dehradun, and Kohima.
Step 1: Examine the nature of the words
Jaipur, Dehradun, and Kohima are all state capitals in India.
Jaipur is the capital of Rajasthan.
Dehradun is the capital of Uttarakhand.
Kohima is the capital of Nagaland.
Tinsukia, on the other hand, is not a state capital. It is a town in Assam, India.
Step 2: Identify the odd one out
Since Jaipur, Dehradun, and Kohima are state capitals, and Tinsukia is a town, Tinsukia is the odd one out.
Thus, correct option is (c).
