Step 1: Understanding the question
The question asks about challenges faced by India in the immediate post-Independence era. These challenges involved shaping the nationhood and establishing democratic, economic, and social systems.
Step 2: Analyzing the options
- (A) To shape an united nation that was accommodative of the diversity in India: This was indeed a challenge after independence, as India had to accommodate its diverse population while forming a unified nation.
- (B) To restructure its economy through structural adjustment programme: This was not an immediate challenge post-Independence. Structural adjustment programmes came much later in the 1980s and 1990s, particularly under economic liberalization.
- (C) To develop democratic practices in accordance with the Constitution: Establishing democracy in line with the newly adopted Constitution was a key challenge immediately after independence.
- (D) To evolve policies that address economic development and eradication of poverty: This was also a major challenge faced post-Independence, as poverty was widespread, and economic development needed to be focused upon.
Step 3: Conclusion
The restructuring of the economy through a structural adjustment programme was not an immediate challenge post-Independence. It became relevant later in India's economic history. Hence, the correct answer is option (B).
