Correct Answer - Option 2 : An element of work entailed in the project

Activity:

Any portion of a project which consumes time or resources and has a definite beginning and an end is called as an activity.

It is denoted by an arrow, but the length of an arrow has no significance.

The symbol above the arrow indicates activity description and the number below indicates activity duration in time units.

Activity is actual performance of a job. It requires time and resources for its completion.

Parallel activities:

The activities which can be performed simultaneously and independent of each other called as parallel activities.

Successor activities:

Activities that can be performed after performance of other activity are known as successor activities.

Predecessor activities:

Activities that are required to be performed before another activity can begin are called as predecessor activities.
