Concept:
- The Thousand Pillar Temple is a Kakatiya-era temple dedicated to Lord Shiva, Vishnu and Surya, built by King Rudra Deva in 1163 CE.
- It stands at Hanamkonda, right next to Warangal, in present-day Telangana.
Step 1: Recall the dynasty behind the temple.
The Thousand Pillar Temple was built by the Kakatiya dynasty, well known for its temple architecture around the Warangal region.
Step 2: Recall the present-day location of that region.
Hanamkonda and Warangal fall within the state of Telangana, which was carved out of Andhra Pradesh in 2014.
Step 3: Eliminate the other options.
Kerala, West Bengal and Karnataka have no connection to the Kakatiya temple-building tradition, so only Telangana remains correct.
Final Answer: Telangana (option 3)
