Explanation:

Art and architecture of Kakatiya Dynasty

• The iconic Kakatiya Thoranam was built by Rudramadevi’s father in the 12th Century. This ornate arch is said to have many similarities with the gateways at the Sanchi Stupa and is also the emblem of Telangana.
• The scenic Pakhal lake in Warangal was built by Ganapathi Deva.
• The 1000 pillar temple in Warangal was built during the Kakatiya Rule and is another example to the exquisite Kakatiya Architecture.
• The Koh-i-Noor Diamond, which is now among the jewels set in the British Crown, was mined and first owned by the Kakatiya Dynasty.

Hence both statements are correct.
