Question

Match the following basins in Group I with their corresponding formations in Group II. \[ \begin{array}{|c|c|} \textbf{Group I} & \textbf{Group II} \\ P. Cauvery & 1. Lohardih \\ Q. Damodar & 2. Tiratgarh \\ R. Chhattisgarh & 3. Raniganj \\ S. Indravati & 4. Kallamedu \\ \end{array} \]

• A. P-4, Q-3, R-2, S-1
• B. P-3, Q-4, R-2, S-1
• C. P-4, Q-1, R-3, S-2
• D. P-2, Q-3, R-1, S-4

Hint:

Mnemonic: Kallamedu–Cauvery (K–C), Raniganj–Damodar (R–D), Tiratgarh–Chhattisgarh (Ti–Ch), Lohardih–Indravati (Lo–In).

Answer 1

The Correct Option is A

Step 1: Recall characteristic formations of each basin.
- Cauvery Basin (Meso–Cenozoic, SE India): well-known Kallamedu Formation (Late Cretaceous). $\Rightarrow$ P–4.
- Damodar Basin (Gondwana, eastern India): classic coal measures including the Raniganj Formation. $\Rightarrow$ Q–3.
- Chhattisgarh Basin (Proterozoic): includes the Tiratgarh Sandstone/Formation. $\Rightarrow$ R–2.
- Indravati Basin (Proterozoic, Bastar craton): includes Lohardih Formation. $\Rightarrow$ S–1.

Step 2: Compile the mapping.
P–4, Q–3, R–2, S–1 $\Rightarrow$ option (A).

Final Answer: \[ \boxed{\text{(A) P-4, Q-3, R-2, S-1}} \]
