What is one disadvantage of primary research?

Primary research is often considered time-consuming and costly because it involves the collection of original data directly from sources, which requires significant planning, resources, and coordination. This can include designing surveys, conducting interviews, or performing experiments, all of which demand time for execution, as well as financial investment in tools, personnel, and participant incentives.

In contrast, secondary research involves analyzing existing data that has already been collected by someone else; this process is generally quicker and less expensive. While primary research can yield highly specific and relevant insights tailored to the researcher's specific questions, the trade-off is that it requires a greater commitment of time and resources, making Option B the correct choice.
