Delimitations are self-imposed boundaries that the researcher chooses in order to narrow down the study to a manageable focus, such as restricting the sample to certain grades or institutions. They indicate what will be included and what will be excluded by design. These boundaries help maintain clarity and feasibility without being imposed by external constraints. Therefore, intentional scope boundaries are correctly called delimitations.
Option A:
Limitations refer to weaknesses or constraints that the researcher cannot fully control, such as time, resources or measurement imperfections. They may restrict the generalisation of findings but are not deliberately chosen boundaries. Hence, limitations are different from the intentionally set scope defined in the stem.
Option B:
Delimitations are decided at the planning stage so that the research remains coherent and realistic with available resources. By specifying these boundaries explicitly, the researcher makes the focus and context of the study transparent. This matches the description in the question, confirming that delimitations is the appropriate term.
Option C:
Assumptions are underlying conditions or statements accepted as true without proof for the purpose of the study, such as the honesty of respondents. They do not define the geographic, temporal or conceptual confines of the research. Thus, assumptions cannot be equated with the boundaries referred to in the stem.
Option D:
Hypotheses are tentative predictions about relationships between variables to be tested empirically. They arise from the research problem and literature rather than defining the limits of the studyโs scope. Therefore, hypotheses are not the correct completion.
