Answer:
The correct answer would be option C, The Encoding Specificity Principle.
Explanation:
According to the Encoding Specificity Principle, it will be easier for a human mind to retrieve information if the external conditions or environment at the time of retrieval are similar or same to those of the conditions or environment when the information was stored. The most common example can be taken of the Examination Hall. If a student has studied in the same class where he is giving the exam, it is more likely for him to recall the questions which he studied in the same class.
So In this question, it is suggested that students should study in a variety of places according to the material of study, so that they can retrieve it easily by remembering the locations where they studied. So this suggestion solves a problem raised by the Encoding Specificity Principle.
