From option (a):PONPMOQP

M N PO Q M N O P Q M N O P Q M N O QP (not follows logical pattern)

From option (b):OPNPMOPQ

M N OP Q / M N O P Q / M N O P Q / M N O PQ (Follows logical pattern)

From option (c):OPPNMOQP

M N OP Q M P O N Q M N O P Q M N O QP (not follows the logical pattern)

From option (d):PONPOMPQ

M N PO Q M N O P Q O N M P Q M N O PQ (not follows logical pattern)
