Step 1: Recall the “seven sins of memory” (Schacter).
These concepts describe characteristic ways in which memory can fail or distort.
Step 2: Match each concept with its description.
Transience refers to the weakening of memory traces over time, hence it matches with (iii) accessibility of memory decreases over time.
Misattribution involves remembering content but confusing its source, so it matches with (i) source of memory is confused.
Absentmindedness is forgetting due to failures of attention at encoding or retrieval, which matches (iv) forgetting caused by lapses in attention.
Persistence refers to the unwanted recurrence of memories, matching (ii) inability to forget undesirable memories.
Step 3: Identify the correct option.
The correct mapping is:
P-(iii), Q-(i), R-(iv), S-(ii), which corresponds to option (A).
Final Answer: (A)
