The earliest completion time for the project using a Gantt chart is d. 13 weeks
A Gantt chart is a horizontal bar chart that displays the tasks or events that make up a project's planned schedule between start and finish dates. In the Gantt chart, each bar represents a task, and the dates are arranged horizontally.
Teams can better plan their work around deadlines and allocate resources when they use Gantt charts. Gantt charts are another tool used by project planners to keep an overview of their projects. They show, among other things, how dependent tasks, milestones, and tasks with different start and end dates relate to one another.
Any activity's earliest completion time (EC) is equal to its earliest start time plus its anticipated duration (its duration). The project's earliest completion date coincides with the earliest date that the final activity was completed. The duration of the activity plus its earliest start time equals the activity's earliest finish time. Here, the earliest time is 13 weeks.
