Why did the Indian government decide to take a 'plan holiday' at the launch of the 4th FYP?

Both options 1 and 2.

The Fourth Plan was due to start in 1966. By this time, the novelty of planning had declined considerably, and moreover, India was facing an acute economic crisis. The government decided to take a ‘plan holiday’. Though many criticisms emerged both about the process and the priorities of these plans, the foundation of India’s economic development was firmly in place by then.
