Answer:
The answer is "Least recently used policy".
Explanation:
It is the page replacement policy, which uses a less frequent substitute. It adds a registry from each frame that includes the last time the program, that views within the frame, and use a "logical clock" for each of the data references, that made to change by a tick.
This replacement strategy is often used to substitute its least currently utilized cache line or page, and it is realistic and best implemented among the substitution policies.
