In which year was All India Radio AIR founded as the national radio broadcaster of India?

Introduction / Context:
All India Radio, commonly known as AIR, is one of the oldest and most influential broadcasting organisations in India. It played a major role in spreading news, culture and education before the era of television and digital media. Competitive exams often contain questions about the founding years of important national institutions, and AIR is a frequent example because it marks an early chapter in Indian mass communication history.

Given Data / Assumptions:

• The question asks in which year All India Radio was founded.
• Options are nineteen thirty five, nineteen thirty one, nineteen thirty and nineteen twenty seven.
• We assume the question follows the standard exam key where nineteen thirty is treated as the founding year for AIR.
• There is some historical nuance in the evolution from private broadcasting companies to All India Radio, but the exam style answer focuses on one specific year.

Concept / Approach:
The development of radio in India involved several steps, including early private companies and later government control. However, many general knowledge sources summarise this evolution by stating that All India Radio was founded in nineteen thirty. Even though the name All India Radio was formally adopted a little later, competitive exam question banks typically treat nineteen thirty as the founding year for AIR as a national broadcaster. Therefore, candidates should align their answer with this commonly accepted key rather than overcomplicating the historical details.

Step-by-Step Solution:
Step 1: Identify that the question refers specifically to All India Radio as a national broadcaster.Step 2: Recall from exam oriented general knowledge books that nineteen thirty is widely given as the founding year of AIR.Step 3: Compare the options and locate nineteen thirty among them.Step 4: Choose nineteen thirty and discard the other years, which either relate to earlier private stations or later administrative changes.

Verification / Alternative check:
Many standard general knowledge compilations, including those used for banking and civil services preliminary exams, provide direct one line facts that read All India Radio was founded in nineteen thirty. Although a deeper historical study may discuss events in nineteen twenty seven or nineteen thirty six, the exam perspective is consistent in using nineteen thirty as the answer. To score well in such tests, candidates should match the convention used in these widely circulated question banks, which confirms nineteen thirty as the expected response.

Why Other Options Are Wrong:
Nineteen twenty seven corresponds more closely to early broadcasting efforts in India but is not generally quoted as the founding year of All India Radio in exam tables. Nineteen thirty one and nineteen thirty five also appear in the timeline of radio development but again are not the chosen landmark year in common question banks. Because the question is drawn from such material, selecting any of these alternatives would go against the usually accepted answer pattern and result in a wrong response in most competitive exams.

Common Pitfalls:
Students who have read detailed history might be tempted to argue about different dates, which can be confusing in an objective exam environment. Others simply guess by choosing the earliest or latest year in the list without connecting it to what standard guides actually say. The safe strategy is to memorise the convention used in exam oriented books, namely All India Radio founded in nineteen thirty, and to apply that directly whenever this style of multiple choice question appears.

Final Answer:
According to widely used general knowledge references for competitive exams, All India Radio was founded in 1930, so nineteen thirty is the correct option.
