Book structure (front matter to back matter): Arrange these in the order they typically appear— a. Index, b. Content (table of contents), c. Title, d. Chapter, e. Introduction.

Introduction / Context:
Most books follow a conventional layout from front matter to core chapters and then back matter. Knowing this order helps in quickly locating information and reflects general publishing practice.

Given Data / Assumptions:

• Title page appears first.
• Introduction (or Preface/Foreword) precedes the table of contents in many exam conventions for reasoning problems.
• Contents (table of contents) lists chapters; chapters form the main body.
• Index appears at the end (back matter).

Concept / Approach:
Sequence standard components as readers encounter them: title page → introductory material → contents → chapters → index.

Step-by-Step Solution:

Verification / Alternative check:
Check any standard text; back matter such as the index is always at the end.

Why Other Options Are Wrong:
They misplace index or mix front matter order.

Common Pitfalls:
Confusing introduction with a chapter; placing index before contents.

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