Which of the following could be the one missing data item for the above set, if the mode is 4?
A.0
B.3
C.4
D.5

Can somebody plz check this, I think it's D

the mode is the value that occurs most often
0 and 4 already appear twice
so, if the mode is 4, then 4 appears the most times.
so, not D
thank you
