Explanation
PERT (Program Evaluation and Review Technique) is correct because it explicitly models tasks as a network of nodes connected by dependency arrows, making predecessor/successor relationships the core of how it works - you cannot build a PERT chart without defining what comes before and after each activity. A Gantt chart shows tasks on a timeline with bars indicating duration, but does not inherently encode dependencies (though modern tools can overlay them, the chart type itself is not dependency-based). A Milestone chart only marks key events or deliverables, with no representation of task relationships at all. A Calendar chart simply maps tasks to calendar dates without any dependency logic.
Memory tip: Think "PERT = Predecessor/Successor chain" - the P in PERT can remind you of predecessors, and the network diagram it produces looks like a chain of connected nodes flowing from start to finish.
