Answer:
The correct option is (B)
Step-by-step explanation:

For that, he gets the research done already known population who have been briefed about the idea and are expected to provide positive feedback. This is an example of advocacy research.
Sugging is just pretending to conduct a research but the main aim is to sell the product. So this option is incorrect.
Other options are incorrect as they focus on deriving the outcome but advocacy research focus on just supporting the outcome.
