Explanation

Pair 1 — Incorrectly matched: Besnagar (ancient Vidisha, Madhya Pradesh) is famous for the rock-hewn Heliodorus Pillar (Khamba Baba) erected around 113 BCE by Heliodorus, an ambassador of the Indo-Greek King Antialcidas. The Brahmi inscription dedicates the column to Vasudeva, making it a seminal Vaishnavite monument, not a Shaivite shrine.

Pair 2 — Correctly matched: The Bhaja Caves (near Pune, Maharashtra) consist of 22 rock-cut Buddhist chambers dating to the 2nd century BCE, belonging to the Hinayana (Theravada) Buddhist tradition and featuring an apsidal chaityagriha and monolithic stupas.

Pair 3 — Correctly matched: The Sittanavasal Caves (Pudukkottai district, Tamil Nadu) are rock-cut monastic caverns (Arivar Koil) belonging to the Jain tradition, featuring polished rock beds used by Jain ascetics for penance (Sallekhana) and murals depicting the Samavasarana.

Therefore, only two pairs are correctly matched.
