Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A: Thrashing occurs when a process spends more time on paging than executing.
Reason R: It happens when the degree of multiprogramming is too low and frames are insufficient.
In the light of the above statements, choose the most appropriate answer from the options given below:
Both A and R are correct and R is the correct explanation of A

Correct answer: C
Thrashing is a phenomenon in virtual memory systems where a process spends more time paging than executing. This occurs when the degree of multiprogramming is too high, leading to insufficient frames per process.
Assertion A correctly describes this behavior. However, Reason R is incorrect because it states the degree is too low. Therefore, A is correct but R is not.
