Correct

Which of the following is also a B-Tree of order 3?


              (29 # _ )
            /           \
           /             \
          /               \
      (21 # _)            (37 # 50 )
     /    \             /     |     \
    /      \           /      |      \
(7,9,11)   (21,23)  (29,30) (37,49)  (50,100)
