Among the given options, the Gondwana Rock System is the youngest in terms of geological age. Gondwana rocks largely consist of sedimentary sequences formed during the Late Palaeozoic to Mesozoic periods. Many Gondwana basins of India contain important Permian-age coal-bearing formations.

In contrast, the Dharwar rocks are much older and are mainly associated with the Archaean age. Therefore, among these four systems, Dharwar represents one of the oldest rock sequences.

The Cuddapah Rock System is mainly associated with the Proterozoic period. The Cuddapah Basin contains a thick sedimentary succession, while the Vindhyan Rock System is also Proterozoic, particularly associated with Meso- to Neoproterozoic sedimentary sequences.

Thus, the broad chronological sequence can be understood as—

Dharwar → Cuddapah → Vindhyan → Gondwana
