Arrange the following sections of a research dissertation in correct sequence:
A. Acknowledgement
B. Research Methods
C. Discussion
D. Literature Review
Choose the correct answer from the options given below:

The correct answer is A, D, B, C — that is, Acknowledgement → Literature Review → Research Methods → Discussion.

To understand why this sequence is correct, let us walk through the standard structure of a research dissertation and the logical role each section plays.

Step 1 — Understanding the Standard Dissertation Structure
A research dissertation follows a well-established, logical order. Each section builds upon the previous one, guiding the reader from the researcher's personal acknowledgements through to a final critical discussion of the findings. The four sections given here — Acknowledgement (A), Research Methods (B), Discussion (C), and Literature Review (D) — all fall within this standard structure.

Step 2 — A: Acknowledgement (comes first among these four)
The Acknowledgement section is placed at the very beginning of a dissertation, right after the title page and abstract (if present), and before the main body of the work begins. Here, the researcher thanks supervisors, institutions, family, and others who supported the work. Since it is a prefatory (preliminary) section, it naturally comes before any academic content. This places A first in the sequence.

Step 3 — D: Literature Review (comes second)
After the preliminary sections, the dissertation enters its main body. The Literature Review is always the first substantive chapter of academic content. In this section, the researcher surveys existing published research related to the topic. This is done before describing one's own methods, because the researcher must first establish what is already known, identify the gap in knowledge, and justify why the new study is needed. This places D second.

Step 4 — B: Research Methods (comes third)
Only after the existing body of literature has been reviewed can the researcher explain how they conducted their own study. The Research Methods chapter describes the design, data collection tools, sampling, and procedures used. It logically follows the Literature Review because the chosen methods are often informed by or contrasted with prior research approaches. This places B third.

Step 5 — C: Discussion (comes fourth / last among these)
The Discussion section comes after the findings have been presented. Here, the researcher interprets the results, explains their significance, connects them back to the Literature Review, and draws conclusions. Since discussion requires both the methods and the results to have already been described, it is always placed toward the end of the dissertation. This places C fourth.

Summary of the Correct Sequence:

A (Acknowledgement) → Prefatory/preliminary section, placed before main content.
D (Literature Review) → First main chapter; establishes existing knowledge and research gap.
B (Research Methods) → Second main chapter; explains how the study was conducted.
C (Discussion) → Later chapter; interprets results and draws conclusions.

This gives us the order: A → D → B → C, which corresponds to option A, D, B, C.
