Thrashing : in thrashing maximum CPU time is wasted in I/O and page faults . So CPU utilization is less so scheduler tries to insert more page in its ready queue so that CPU utilization can be increased . so degree of multiprogramming will not be decresed . 

 so Ans (c) . implies excessive page I/O
