Step 1: Read the question.
We must say which larger plateau the Telangana Plateau is a part of.
Step 2: Location of Telangana Plateau.
The Telangana Plateau lies in southern India and is made of old hard igneous and metamorphic rocks with rivers like the Godavari and Krishna flowing through it.
Step 3: The big plateau of South India.
Most of peninsular South India is covered by one huge raised landmass called the Deccan Plateau.
Step 4: Connect them.
The Telangana Plateau is the northern part of this Deccan Plateau, so it is one piece of that larger region.
Step 5: Rule out the others.
The Malwa Plateau and Chota Nagpur Plateau are in central and eastern India. The Central Highlands are also further north. None of these contains the Telangana Plateau.
Step 6: Conclude.
The Telangana Plateau is a part of the Deccan Plateau.
\[ \boxed{\text{Deccan Plateau}} \]
