Answer
Correct Answer: A-4, B-3, C-2, D-1
Explanation
Introduction / Context:Classic DOS-era utilities remain foundational knowledge for system basics. This mapping reinforces what common commands and tools do: screen handling, virus scanning, disk partitioning, and version reporting.
Given Data / Assumptions:
- CLP is taken here to denote the screen-clearing command used in DOS contexts (historically written as CLS; the question uses CLP, which we treat as a local shorthand).
- MSAV is Microsoft's anti-virus utility.
- FDISK is the partitioning tool for hard disks.
- VER prints the DOS (or command interpreter) version.
Concept / Approach:
Associate each tool with its primary function. The focus is on standard textbook roles rather than switches or advanced flags.
Step-by-Step Solution:
A (CLP) → clear screen operation ⇒ 4.B (MSAV) → anti-virus utility ⇒ 3.C (FDISK) → disk partition creation/management ⇒ 2.D (VER) → display version information ⇒ 1.Verification / Alternative check:
Try typical command invocations: CLS clears the console; VER prints a version banner; FDISK launches the partition menu; MSAV scans for known virus signatures in its era.
Why Other Options Are Wrong:
Swapping VER with FDISK or MSAV misstates their capabilities; pairing CLP/CLS with anything other than screen clearing contradicts standard documentation.
Common Pitfalls:
Confusing CLP with CLS; also, assuming FDISK formats disks (formatting is a separate step after partitioning).
Final Answer:
A-4, B-3, C-2, D-1
