Option 1 -> Standing Plans are ongoing plans used for recurring activities and are modified periodically as business needs evolve (e.g., policies, procedures, rules).
Option 2 -> Single-use Plans are designed for one-time specific objectives and are discarded once the goal is achieved (e.g., project plans, budgets for specific events).
Option 3 -> Short-term plans are temporary plans covering a brief period (usually up to one year) and are replaced by new plans rather than modified continuously.
Option 4 -> Strategic plans are long-term directional plans that guide overall organizational goals but typically undergo comprehensive revisions rather than frequent modifications.
Hence, Option 1: Standing Plan -> Standing plans are developed once to address recurring situations and are modified from time to time to adapt to changing business needs, making them reusable and flexible frameworks for organizational activities -> correct
