Solution

Basic page replacement order is:

First, location of desired page is found from disk.

Then, if no free frame is available, page replacement algorithm is applied.

Then, desired page is brought into newly freed frame and page table and frame table are updated.

Finally, the process is restarted from the instruction that caused the trap.

So, correct order is:

$C,A,D,B$

Correct option is:

$\boxed{(c)\ C,A,D,B}$
