Consider the following pairs:

Medieval Indian State	Present Region
1. Champaka	Central India
2. Durgara	Jammu
3. Kuluta	Malabar

Which of the above pairs is/are correctly matched?

The correct option is 2 only.

To understand why this is the correct match, let us analyze each of the historical pairs one by one:

1. Champaka:
Champaka was an ancient and medieval hill state in India. It is identified with the modern-day Chamba region, which is located in the state of Himachal Pradesh (Himalayan region), and not in Central India. Therefore, Pair 1 is incorrectly matched.

2. Durgara:
Durgara was a medieval state representing the Dogra territories. Historically, this state is associated with the Jammu region of Jammu and Kashmir. Therefore, Pair 2 is correctly matched.

3. Kuluta:
Kuluta was an ancient and medieval principality located in the upper valley of the Beas River. This corresponds to the modern-day Kullu region in Himachal Pradesh, not the Malabar region (which is along the southwestern coast of India in Kerala). Therefore, Pair 3 is incorrectly matched.

Consequently, only pair 2 is correctly matched, making "2 only" the correct answer.
