A) Program Structure.
Reason: Thrashing occurs when page fault rate increases which in turn increases the page fault rate which results in less amount of productive work.
It depends on which type of page replacement algorithm we use, if we use global page replacement algorithm then thrashing will occur. We can minimize the effects of thrashing by using local page replacement.

Can anyone explain. How is this possible?
Logically we can say that all this can affect directly or indirectly the problem of thrashing. Bcos if program size is larger then more page blocks required. In the same way, if primary storage is significantly smaller then there is also the problem of thrashing.

In virtual memory systems, thrashing may be caused by programs or workloads that present insufficient locality of reference, if the working set of a program or a workload cannot be effectively held within physical memory, then constant data swapping, i.e., thrashing, may occur.

All three factors—program structure, program size, and primary storage size—can significantly impact the occurrence and severity of thrashing in a computer system.
Therefore, the correct answer is "all of the above. ".

Why program structure?
There is no link of thrashing with program structure it should be primary storage size.

Why program structure? thrashing is affected by paging.

I think this will be for lower primary-storage size.
Prince Srivastava said:

Yes it will be affected by primary storage size.

Yes it depends on the Primary Storage.

I too think C is the right answer.
