Solution
Option 1 -> Measurement involves quantifying actual performance but does not involve matching it with standards.
Option 2 -> Corrective action is taken after comparison to address deviations between performance and standards.
Option 3 -> Comparison is the process of matching actual performance against predetermined standards to identify variations.
Option 4 -> Feedback provides information about results but is not specifically about matching performance with standards.
Hence, Option 3: Comparison -> Comparison is the control element that directly involves matching actual performance with predetermined standards to determine if there are any deviations or variances that need attention -> correct
