Answer:
The correct answer is letter "E": applied research.
Explanation:
Applied research is a study conducted to solve a specific real-world problem typically business, medicine, or education-related in an attempt to develop new methods to do things using existing knowledge. Finding new technologies is the main goal of applied research.
One of the disadvantages of applied research is that the findings only apply to the field of study, thus, they cannot be generalized to other subjects.
