ANS: A
Although the study will receive much criticism as to its validity, the researcher has operationalized the variable in a correct manner. An operational definition is derived from a set of procedures or progressive acts that a researcher performs to receive sensory impressions that indicate the existence or degree of existence of a variable. An operational definition is developed so that a variable can be measured or manipulated in a concrete situation. They must be independent of time or setting so that variables can be investigated at different times and in different settings.

There is no way to determine what the researcher will actually take into account for this definition.
