The Government of India decided to introduce a new 100 rupee commemorative coin featuring the image of which former Prime Minister of India?

Introduction / Context:
Commemorative coins are issued by governments to honour important national leaders and mark significant anniversaries. In India, special denomination coins have been released to pay tribute to prominent figures such as former Prime Ministers. Around 2018, the Government of India decided to introduce a new 100 rupee coin in memory of a former Prime Minister who had recently passed away. This question tests your knowledge of which leader was honoured through this commemorative coin.

Given Data / Assumptions:

The denomination of the coin is 100 rupees.
It is a commemorative coin issued by the Government of India.
The coin features the image of a former Prime Minister.
The options are Jawaharlal Nehru, Indira Gandhi, Atal Bihari Vajpayee, and Rajiv Gandhi.

Concept / Approach:
To answer, you need to recall recent political and economic news. In 2018, a 100 rupee commemorative coin was approved to honour former Prime Minister Atal Bihari Vajpayee, who passed away in the same year. The coin featured his portrait and related inscriptions. Other former Prime Ministers like Jawaharlal Nehru, Indira Gandhi, and Rajiv Gandhi have been honoured in many ways, but the specific new 100 rupee coin launched during that period was associated with Atal Bihari Vajpayee. Recognising that link helps you identify the correct option.

Step-by-Step Solution:
Step 1: Recall the news about a special 100 rupee coin announced near the time of Atal Bihari Vajpayees birth anniversary after his passing. Step 2: Remember that this coin was explicitly described as a commemorative coin featuring Vajpayees portrait. Step 3: Check the options and find the name that matches this memory. Step 4: Identify Atal Bihari Vajpayee among the four former Prime Ministers listed. Step 5: Select Atal Bihari Vajpayee as the correct answer.

Verification / Alternative check:
You can verify by matching the timing. Atal Bihari Vajpayee passed away in 2018, and soon after, the Government of India announced a commemorative coin for him. Jawaharlal Nehru, Indira Gandhi, and Rajiv Gandhi had been commemorated earlier in various forms, but there was no major new 100 rupee coin announcement for them around 2018. This timing and the widely reported coin release confirm that the new 100 rupee coin in the question refers to Atal Bihari Vajpayee.

Why Other Options Are Wrong:
Jawaharlal Nehru: The first Prime Minister of India, honoured in many ways, but not the specific new 100 rupee coin described in this question. Indira Gandhi: Also commemorated separately, but no widely publicised 100 rupee coin launch in 2018 for her. Rajiv Gandhi: Another former Prime Minister remembered through other means, yet not the subject of the 100 rupee coin announced at that time.

Common Pitfalls:
Candidates may confuse various commemorative stamps, coins, and schemes dedicated to different leaders and assume that any well known Prime Minister might be the answer. Others may guess based on personal familiarity with the name instead of recalling the specific news about the 100 rupee coin. To avoid such confusion, link each major commemorative announcement with a clear mental image: for this coin, imagine the portrait and name of Atal Bihari Vajpayee on a new, special denomination coin.

Final Answer:
The new 100 rupee commemorative coin described in the question features former Prime Minister Atal Bihari Vajpayee.
