• (B) The PCB includes the program code and data segments of the process. -
  • This statement is NOT CORRECT. The PCB does not contain the program code and data segments. Instead, it includes metadata about the process.
• (C) The PCB stores the process's memory management information, such as page tables and segment tables. -
  • This statement is CORRECT. The PCB stores crucial memory management information, including page tables and segment tables, which are necessary for the process's execution.
• (D) The PCB is used to track process scheduling information and CPU registers for process execution. -
  • This statement is CORRECT. The PCB is indeed used to track scheduling information and CPU registers, which are essential for context switching and process management.
