Answer:
A) primary research
Explanation:
Primary research is defined as a methodology used by researchers to collect data directly, rather than depending on data collected from previously done research. Technically, they “own” the data.
Primary research is solely carried out to address a certain problem, which requires in-depth analysis.
Companies that specialize in interviewing, observing, recording and analysing the behaviour of those who purchase good and service are called primary research suppliers.
