The correct option is Chalukyas.
Explanation
The political vacuum created in the Deccan following the decline of the Vakataka dynasty (late 5th to early 6th century CE) was primarily filled by the Chalukyas of Badami (Vatapi). This dynasty played a foundational role in the evolution of Indian rock-cut and structural temple architecture, marking the beginning of the distinct Deccan style.
Option Analysis
- Chalukyas Chalukyas: Correct. The Chalukyas of Badami established their authority in the Deccan around the mid-6th century CE under Pulakeshin I. They are credited with excavating the famous Badami Cave Temples (comprising Brahmanical and Jain caves) and building early structural temples at Aihole and Pattadakal.
- Pallavas Pallavas: Incorrect. The Pallavas were contemporaries of the Chalukyas but ruled the Tondaimandalam region with their capital at Kanchipuram. They are renowned for the rock-cut rathas and shore temples at Mahabalipuram, not the Badami caves.
- Cholas Cholas: Incorrect. While early Cholas existed during the Sangam age, the Imperial Cholas rose to prominence much later (9th century CE) in the Kaveri delta region, succeeding the Pallavas.
- Rashtrakutas Rashtrakutas: Incorrect. The Rashtrakutas succeeded the Chalukyas of Badami in the Deccan around the mid-8th century CE. They are famous for the rock-cut Kailasa Temple at Ellora, not the earlier Badami caves.
Key Takeaway: The Chalukyas of Badami succeeded the Vakatakas in the Deccan and were the patrons of the Badami cave temples, laying the groundwork for the Vesara style of temple architecture.
