Which Indian film star was roped in by the Union Government in June 2017 to promote the Goods and Services Tax (GST) as its brand ambassador?

Introduction / Context:
When the Goods and Services Tax (GST) was introduced in India, the Union Government carried out a wide public-awareness campaign to explain the new tax system. As part of that campaign, a very popular film star was chosen as the brand ambassador to help communicate GST messages to the public. This question asks you to recall which celebrity was roped in for that role in June 2017.

Given Data / Assumptions:

• The campaign is about GST, a major tax reform introduced in 2017.
• The government chose a film star as brand ambassador.
• The selection took place around June 2017.
• Options list Sachin Tendulkar, Salman Khan, Amitabh Bachchan, Aishwarya Rai Bachchan and Akshay Kumar.

Concept / Approach:
The correct association here is with Amitabh Bachchan, one of India’s most recognisable film personalities. The Government of India engaged him to appear in advertisements and awareness messages explaining GST in simple terms. While the other names are also very famous, the specific 2017 GST campaign is linked in news reports and exam guides with Amitabh Bachchan.

Step-by-Step Solution:
Step 1: Recall the year 2017, when GST replaced multiple indirect taxes with a single nationwide tax structure. Step 2: Remember news reports that highlighted Amitabh Bachchan as the face of GST awareness campaigns. Step 3: Compare each option: Sachin Tendulkar is a cricket legend, not primarily a film star; Salman Khan and Akshay Kumar endorse many products but were not the main faces of GST. Step 4: Aishwarya Rai Bachchan is also a film star, but the official GST campaign naming focused on Amitabh Bachchan. Step 5: Therefore, select Amitabh Bachchan as the correct answer.

Verification / Alternative check:
One way to verify is to think of the type of government advertisements you may have seen about GST around its launch. Many featured Amitabh Bachchan speaking in a calm, authoritative tone, explaining that GST would simplify the tax structure. This role is consistent with his frequent appearances in public-interest campaigns, such as those about polio, tourism and cleanliness, reinforcing his link to GST as well.

Why Other Options Are Wrong:
Sachin Tendulkar: A cricketer, not a film star, and not the officially announced GST brand ambassador in June 2017.
Salman Khan: A major actor and brand endorser, but not publicly identified as the GST campaign’s main ambassador.
Aishwarya Rai Bachchan: Internationally famous actress, yet the GST awareness ads were centred around Amitabh Bachchan.
Akshay Kumar: Known for patriotic and socially themed films and endorsements, but not the specific choice for GST promotion at that time.

Common Pitfalls:
Because several of these celebrities regularly appear in public-interest advertisements, candidates may guess based solely on current visibility. Another pitfall is to confuse sports brand ambassadors with policy campaign ambassadors. To avoid this, it helps to pair key schemes with their faces: Swachh Bharat has had multiple faces; GST launch campaign → Amitabh Bachchan is the association usually given in GK notes.

Final Answer:
The film star chosen in June 2017 to promote GST as its brand ambassador was Amitabh Bachchan.
