A: True; processes share their address space.

B: False; process does not share register state and stack to run independently.

C: False; kernel can create any number of threads regardless of number of processors in the system, the point is it can run threads equal to the number of processors simultaneously.

D: False; within a process TLB flush is not required, switching between processes requires flushing although TLB can have ASIDs(address space identifiers) that prevent accessing other process address space hence providing security.
