The question is about identifying the key reform emphasized in the Economic Survey 2024-25 for long-term growth. This is a current affairs question focused on understanding recent government documents and their implications.

The options given are:

• Price control regimes
• Nationalisation of banks
• Public sector expansion
• Systemic deregulation

From the given options, the correct answer is Systemic deregulation.

Explanation:

The Economic Survey is an annual document presented by the Government of India, providing a detailed account of the country's economy over the past year and suggesting future reforms. For the 2024-25 Economic Survey, "Systemic deregulation" is emphasized as a key reform for sustaining long-term growth. Here’s why:

• Systemic Deregulation: This refers to the reduction of government oversight and increases market efficiency by removing unnecessary regulations, thus promoting entrepreneurial activities and economic freedoms. This aligns with global trends focusing on lean governance for economic expansion.
• Others: The other options like "Price control regimes" and "Nationalisation of banks" are counterproductive to free-market operations, and "Public sector expansion" contradicts the recent trend of prioritizing private sector growth and efficiency. Therefore, these options do not align with the long-term growth strategies typically highlighted in recent economic surveys.

By understanding these points, it's clear that systemic deregulation is prioritized for long-term growth, reflecting a shift towards enabling a more dynamic and competitive economic environment.
