Step 1: Use mining regions:
Recall the famous mining places of Rajasthan: Zawar, Rampura Agucha, Khetri and Dariba. Each one is tied to a metal.
Step 2: Assign metals to places:
Zawar and Rampura Agucha: zinc and lead. Dariba: zinc and lead. Khetri: copper. No main iron mine is on this list.
Step 3: Mark each statement:
A (Zinc) is in the list, B (Copper) is in the list, C (Iron) is not, D (Lead) is in the list.
Step 4: Choose the option:
We need the option with A, B and D and without C. Options 1, 2 and 3 each contain C, so they fail. Option 4 has A, B and D.
Step 5: Answer:
Option 4 is correct.
Final Answer:
The mineral combination for Rajasthan is zinc, copper and lead, option 4.
\[ \boxed{\text{4 (A, B and D only)}} \]
