The correct answer is B) The cognitive process of critically evaluating disciplinary insights and creating common ground among them to construct a more comprehensive understanding.
That is a good definition of interdisciplinary integration.
What is going to happen here is that the new understanding would be the product of the evaluation of these disciplines that come to strengthen the knowledge and is the result of the integrative process.
This interdisciplinary integration is going to be useful to synthesize concepts and information needed to improve the quality and focus of research or any investigative project.
