6. (6%) A multiprogramming operating system uses partition. The available memory Load A as Al is 4096KB. The program A needs 235KB. The program B needs 86KB. The Load B as B1 program C needs 1833KB. The program D needs 347KB. If a program is loaded Load C as Ci many times, every load will need an individual memory allocation. (That is, Load D as Di loading program B two times will cost 172 KB). We run programs as the order Remove Ci described in the table. Load A as A2 a. (2%) After loading A as A2, how much memory is unused? Load A as A3 b. (2%) Can we load the program C as C2 successfully? Why or Why not? Load C as C2 c. (2%) If we want to load c2 successfully, what should we do
