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 option is A, D, B, C.

To understand why this is the correct sequence, let us look at the standard structure of a research dissertation:
1. A. Acknowledgement: This is part of the preliminary pages of a dissertation. It appears at the very beginning, before the main body chapters, where the researcher expresses gratitude to advisors, institutions, and supporters.
2. D. Literature Review: This is typically the second major section (often Chapter 2) of the main body of a dissertation. It provides the theoretical background, reviews existing research relevant to the study, and identifies the research gap.
3. B. Research Methods: This section (usually Chapter 3) follows the literature review. It details the methodology, research design, participants, data collection tools, and analysis techniques used to conduct the study.
4. C. Discussion: This section comes after the results have been presented. It interprets the findings, compares them with previous studies (from the literature review), discusses implications, and acknowledges limitations.

Therefore, the logical and standard academic sequence of these sections is Acknowledgement (A) ⇒ Literature Review (D) ⇒ Research Methods (B) ⇒ Discussion (C), which corresponds to the sequence A, D, B, C.
