When an activity is called a critical activity?

When an activity is called a critical activity? Correct Answer When earliest start time (EST) plus the time taken by it is equal to the latest finish time (LFT)

An activity is called critical activity if and only if the earliest start time (EST) plus the time taken by it is equal to the latest finish time (LFT). In other words, if an activity is delayed from the actual timeline and because of this if it affects the entire project duration, then the activity is known as a critical activity.
