Step 1: Understanding the Question:
The key word is consensus, which means a general agreement among leaders of different views.
Step 2: Think of the leaders.
Nehru, the Congress, the socialists and even many industrialists accepted planning. The Bombay Plan of industrialists also asked for a strong role of the state.
Step 3: Look for planning in the options.
Option (4) talks about a design or plan. This is the same idea as the Five Year Plans.
Step 4: Remove the others.
Options (1) and (2) depend on private actors and market forces, which were not the agreed route. Option (3) asks to follow the colonial path, which every nationalist leader opposed.
Step 5: Conclude.
Option (4) is the only one that all groups agreed on.
Final Answer:
Planning by the government was the agreed route. Option (4) is correct.
\[ \boxed{\text{Option 4}} \]
