In India, government coins are produced at official mints. At which combination of locations are coins currently minted for circulation by the Government of India?

Introduction / Context:
Knowledge of where Indian coins and currency are produced is a common topic in general awareness exams. While banknotes are printed at currency presses, coins are manufactured at government mints. This question asks for the correct combination of cities where official mints of the Government of India are actively involved in coin production.

Given Data / Assumptions:

• The focus is on mints that produce coins for the Government of India.
• The options list different combinations of major Indian cities.
• Some cities mentioned are important but do not host a government coin mint.
• The correct answer must include all current mint locations.

Concept / Approach:
The Government of India operates mints at four main locations: Mumbai in Maharashtra, Kolkata in West Bengal, Hyderabad in Telangana, and Noida in Uttar Pradesh. These facilities are responsible for minting coins of various denominations. The approach is to remember this set of four and match it with the option that lists exactly these cities, without including non mint locations or omitting any of the four.

Step-by-Step Solution:
Step 1: Recall that there are four principal mints in India.Step 2: List them mentally as Mumbai, Kolkata, Hyderabad, and Noida.Step 3: Compare this list with each option provided.Step 4: Option D exactly matches all four locations without adding extra cities or missing any.Step 5: Select option D as the correct combination.

Verification / Alternative check:
Official information from the India Government Mint and reputable general knowledge sources consistently list these four cities as current mint locations. Noida is often the city that candidates forget, so double checking for its presence in the options is a useful verification step. Once confirmed, it is clear that only option D is correct.

Why Other Options Are Wrong:
Option A: Delhi is the national capital but does not host a coin mint; Noida nearby in Uttar Pradesh does.Option B: Again, Delhi and Kolkata appear, but Mumbai is missing and Noida is not included.Option C: This combination includes Bangalore and Delhi, neither of which are coin mint locations.Option E: Chennai and Nagpur are not among the official Government of India mints for coins.

Common Pitfalls:
Candidates often assume the capital city must have a mint and hence choose any option that includes Delhi. Another common mistake is overlooking Noida, which is in the National Capital Region but located in Uttar Pradesh, leading to confusion. Remembering the exact four cities and their states is essential for accuracy.

Final Answer:
The correct answer is Mumbai, Kolkata, Hyderabad, Noida.
