Concept:Memory processing follows a fixed order to take in, store, and later use information.
Explanation:First, information is encoded – transformed into a format the brain can store.
Second, the encoded information is retained – held in memory for later use.
Third, the stored information is retrieved – recalled when needed.
This sequence is universal in memory research.
Option A starts with Retention, which is wrong because information cannot be retained before it is encoded.
Option B and C also mix the order incorrectly.
Only option D follows the correct flow: Encoding → Retention → Retrieval.
Answer:The correct sequence is Encoding → Retention → Retrieval, which is option D.
