From option (a):cpdpdbdc

b c d p p b c d p pd c b p p b dc p p (not follows logical pattern)

From option (b):cpdpbdcd

b c d p p / b c d p p / b c d p p / b cd p p (follows logical pattern)

From option (c):cdppbddc

b c d d p b c p p pb c d p p b dc p p (not follows the logical pattern)

From option (d):pcdpbdcd

b p d c p b c d p pb c d p p b cd p p (not follows logical pattern)
