Which of the following tasks cannot start until other tasks are completed?

An analysis task describes a category of work performed during a project phase, not a scheduling relationship between tasks.

A dependent task, also called a successor task, has a defined relationship with one or more preceding tasks that must be completed before it can start. This dependency relationship is a core concept in project scheduling and is modeled using finish-to-start or other logical relationships. The dependency constrains when the task can begin based on the completion status of other tasks.

A predecessor task is the task that must be completed first - it is the one that another task depends on, not the one that is waiting to start.

An independent task has no dependencies and can be scheduled and started at any time regardless of other tasks' completion status.
