Explanation

– Pair 1 is incorrectly matched: Burzahom (located in the Kashmir Valley) is a celebrated Neolithic and Megalithic site, famous for subterranean pit-dwellings, bone tools, and intentional animal burials. Rock-cut architecture did not exist in the Neolithic era and appeared much later in Indian history.
– Pair 2 is correctly matched: Chandraketugarh (North 24 Parganas, West Bengal) was a flourishing ancient riverine port site dating from the Mauryan through the Shunga-Kushana periods, renowned for exquisite moulded terracotta plaques, figurative figurines, and decorative pottery.
– Pair 3 is correctly matched: Ganeshwar (located in the Sikar district near the Khetri copper belt, Rajasthan) is a premier Chalcolithic site (Ganeshwar-Jodhpura culture) that yielded thousands of indigenous copper artefacts including arrowheads, chisels, celts, and fish-hooks, believed to have supplied copper items to Harappan urban centres.

Thus, pairs 2 and 3 are correctly matched — Option D.
