Here we have 4 cascaded counter of total of 16 bits..So it is equivalent to 16 bit ripple counter..

Hence ripple counter of 16 bit has modulus value  =  216

                                                                         = 65536

Hence to get modulus value of 50000 , no of states which must be deleted = Max no of state possible - 50000

                                                                                                             = 15536

Hence D)  is the correct answer
