Authorship to library — arrange document creation and storage flow Items: a. Paper, b. Library, c. Author, d. Book, e. Pen

Introduction / Context:
This sequence traces the creation of a book and its eventual placement for public access. The logic is from creator and tools to medium, product, and repository.

Given Data / Assumptions:

• Author writes with a Pen on Paper.
• The written work becomes a Book.
• Books are stored/available in a Library.

Concept / Approach:
Respect the production order from human agent to final location.

Step-by-Step Solution:
c (Author) → e (Pen) → a (Paper) → d (Book) → b (Library).

Verification / Alternative check:
Publishing workflows (drafting → manuscript → book → cataloging) support this direction.

Why Other Options Are Wrong:

• They place library before the book exists or misorder the author’s tools.

Common Pitfalls:
Confusing medium (paper) and instrument (pen); instrument is used on the medium.

Final Answer:
c, e, a, d, b
