Operating systems

Four processes A, B, C, and D are started at time 0 and all are in the running state. The following things happen at the following times:

1. At time 5, process A performs a read operation on disk 1.
2. At time 10, process B performs a read operation on disk 2.
3. At time 12, process C perform a read operation on disk 3.
4. At time 14, disk 1  interrupts and returns data.
5. At time 16, disk 3 interrupts and returns data.
6. At time 18, process A performs a write operation on disk 1.
7. At time 21, process C terminates.

At time 25, assuming no other disk operation or disk interrupt has occurred, what is the statement of each of the four processes: ready/running, blocked, or terminated?
