Madhya Pradesh is famous for diamond deposits. In the same resource based analogy, Karnataka is especially associated with which metal?

Introduction / Context:
This is a general knowledge analogy question that links Indian states to the natural resources or minerals for which they are well known. The pair Madhya Pradesh : Diamond highlights the famous diamond producing areas of Madhya Pradesh. You are then asked to find the metal that stands in a similar relationship with Karnataka. The question checks your awareness of important mineral belts and mining locations in India.

Given Data / Assumptions:

Madhya Pradesh is known for diamond deposits, particularly in areas like Panna.
The analogy structure is “state : characteristic mineral”.
Karnataka is another major Indian state with significant mining activity.
The options for Karnataka are Platinum, Copper, Gold and Silver.
We assume standard textbook level knowledge of Indian geography and mineral resources.

Concept / Approach:
The analogy uses a straightforward pattern: state mapped to its most famously associated mineral. Madhya Pradesh is widely taught as a diamond producing state. For Karnataka, the most famous association is with gold, especially due to the historic Kolar Gold Fields and other gold bearing regions. While copper and other metals may also be found in Karnataka, they are not as iconic in general knowledge as gold. Therefore, the parallel mapping is Madhya Pradesh : Diamond :: Karnataka : Gold.

Step-by-Step Solution:
Step 1: Recognise that the first pair connects a state with a mineral resource for which it is particularly famous. Step 2: Recall that Madhya Pradesh has diamond mines, making Diamond the associated mineral. Step 3: Now consider Karnataka and recall its well known mining areas. Step 4: Remember that the Kolar Gold Fields in Karnataka have historically been one of the most famous gold mining regions in India. Step 5: Compare the options. Platinum and copper are not commonly highlighted as the signature minerals of Karnataka in basic GK references. Silver also does not have the same strong association. Step 6: Conclude that Gold is the most appropriate mineral to pair with Karnataka in this analogy.

Verification / Alternative check:
You can verify by quickly reviewing standard geography content. Madhya Pradesh and Andhra Pradesh are noted for diamonds, while Karnataka and neighbouring states are noted for gold deposits. In exam guides, Karnataka is almost always mentioned alongside gold, specifically referring to the Kolar region. Platinum is relatively rare and is not widely mined in Karnataka at an iconic level. Copper deposits are better known from regions like Jharkhand and Rajasthan. Silver is usually linked to polymetallic ores elsewhere. This confirms that gold is the correct and most widely accepted mineral association.

Why Other Options Are Wrong:
Platinum is a very precious metal but is not the classical school level mineral tag for Karnataka. Copper has deposits in parts of India but is not the signature mineral of Karnataka in the way gold is. Silver is produced in India mainly as a by product of lead and zinc mines and is not uniquely associated with this state. None of these alternatives fit as neatly into the state resource analogy as gold does for Karnataka.

Common Pitfalls:
A common mistake is to overthink the question and look for a less obvious metal, especially if you are aware that gold mines in Kolar have faced closure issues. However, in objective type general knowledge questions, the focus is on classical, textbook associations rather than current production volumes. Remembering the strong historical link between Karnataka and gold mining is the key. Avoid reading too much into secondary minerals and match the most prominent and well known resource to the state.

Final Answer:
Madhya Pradesh is known for diamond deposits, and in the same way Karnataka has long been famous for gold, so Gold is the correct answer.
