The correct option is B Median
When a given list of data is arranged in ascending or descending order, then the middle value of ordered data is called median.
For example: 2,3,5,4,2,3,4
Arrange the data whether in ascending or descending order.
2,2,3,3,4,4,5
The middle value is 3. So the median is 3.
So, option D is correct.
