To answer this question, you need to understand the concept of planning.
Option A) Hierarchical planning - This option is correct because hierarchical planning consists of successive representations of different levels of a plan. In hierarchical planning, the overall plan is broken down into smaller, more detailed plans at different levels. This allows for a clear structure and organization of the plan, with each level representing a different aspect or component.
Option B) Non-hierarchical planning - This option is incorrect because non-hierarchical planning does not involve successive representations of different levels of a plan. Non-hierarchical planning is typically more flexible and allows for a more fluid and dynamic approach to planning.
Option C) All of the above - This option is incorrect because non-hierarchical planning is not included in the answer. The correct answer is specifically hierarchical planning.
Option D) Project planning - This option is incorrect because project planning refers to the planning process specifically for a project, which may or may not involve hierarchical planning. Project planning focuses on defining the objectives, scope, tasks, resources, and timeline for a specific project.
Therefore, the correct answer is A) hierarchical planning. This option is correct because hierarchical planning consists of successive representations of different levels of a plan.
