A task displaced by a higher priority task becoming ready enters the

  • A.deleted state
  • B.ready state
  • C.blocked state
  • D.suspended state

Answer: B

It is still perfectly able to run and needs nothing but the processor, which is exactly what the ready state means. Confusing ready with blocked is the commonest error in reading a state diagram, and it matters because a blocked task needs an event to release it.
