Concept:Development planning succeeds only when policies are effectively implemented and monitored.
Explanation:Many Nigerian development plans fail despite having sound objectives and allocated budgets.
The major setback is poor implementation strategies, not the lack of ideas or resources.
Weak implementation includes inadequate supervision, poor coordination, inconsistent policies, and corruption.
Even when foreign aids and funds are available, bad execution causes delay, waste, and abandonment of projects.
This is why past plans, such as the National Rolling Plans, recorded limited success.
Although inadequate funding and skilled manpower shortages exist, the central reason remains the failure to translate plans into action.
Therefore, proper monitoring and control are essential for plan success.
Answer:C. Poor implementation strategies.
