Here before we start we should know : The median is the number that is halfway into the set. To find the median, the data should be arranged in order from least to greatest. If there is an even number of items in the data set, then the median is found by taking the mean (average) of the two middlemost numbers.

Now the 7 nos. can be any number, no more details is given; so median can be any number

which may be 5
less than 5
or greater than 5

Hence option D
