The CPM family of terms commonly includes CPA (Critical Path Analysis), CPP (Critical Path Plotted), MCE (Minimum Cost Expenditure during time–cost trade-off), and CPS (Critical Path Scheduling): effectively, all of the above.

Introduction / Context:
CPM terminology spans analysis, plotting, scheduling, and cost optimization. The question checks familiarity with these related labels that appear in planning literature and practice.

Given Data / Assumptions:

• We consider conventional uses of CPA, CPP, MCE, and CPS in CPM contexts.
• Time–cost optimization (crashing) is within CPM scope.

Concept / Approach:
CPM involves: analyzing networks (CPA), visualizing/plotting critical paths (CPP), scheduling with critical path awareness (CPS), and optimizing direct costs via crashing (MCE) while respecting time constraints. Though acronyms vary by text, all four are encountered under the CPM umbrella.

Step-by-Step Solution:
1) CPA: compute earliest/latest times, floats, and identify the critical path.2) CPP: present critical path graphically for management communication.3) CPS: build schedules honoring critical logic and resource realities.4) MCE: perform time–cost trade-off to minimize expenditure within deadline.

Verification / Alternative check:
Project control texts and exam syllabi often group these under CPM applications: analysis, display, scheduling, and cost optimization.

Why Other Options Are Wrong:

• Options A–D each describe a legitimate CPM facet; choosing only one is incomplete.
• Hence the comprehensive selection is correct.

Common Pitfalls:

• Treating CPM as scheduling only and ignoring cost optimization.
• Assuming plotting/visualization is optional—communication is critical.

Final Answer:
All the above.
