"An attempt to control everything results in controlling nothing". This refers to:

Option 1 -> Management by Objectives focuses on setting specific goals and measuring performance against them, not about selective control mechanisms.

Option 2 -> Management by Control is not a standard management concept and would imply monitoring everything, which contradicts the principle in the statement.

Option 3 -> Management by Exception is based on the principle that managers should focus only on significant deviations from standards rather than monitoring every activity, as trying to control everything becomes counterproductive.

Option 4 -> Remedial Plan refers to corrective actions taken after problems are identified, not a philosophy about what should be controlled.

Hence, Option 3: Management by Exception -> This statement captures the core philosophy of Management by Exception, which recognizes that attempting to monitor and control every single detail and activity leads to inefficiency and ineffectiveness. Instead, managers should focus their attention on significant deviations (exceptions) from normal operations, allowing routine matters to proceed without interference. This approach enables better resource allocation and more effective control -> correct
