Answer:
A. it is a possible answer to a specific question
Step-by-step explanation:
To act as a scientist, a researcher must meet the methodological requirements of a scientific work. This involves creating a hypothesis for the work, which is nothing more than a question to be investigated during the research. The researcher's hypothesis can be confirmed or refuted at the end of the investigative experiment.
For example, an economics researcher might hypothesize about the impact of increased public spending on early childhood education. Then, based on this hypothesis, he or she will investigate with available data whether increased public spending positively affects early childhood education. At the end of the experiment, he confirms or refutes the hypothesis.
Note: This applies to all areas of knowledge.
