Solution

The correct option is C $6$
First arrange the data set in order.
$1, 2, 2, 4, 5, 6, 7$
Here the median is the middle number $= 4$
So, the upper quartile is the median of the higher half of the data.
Then, the middle of the upper half will be $5, 6, 7$
Therefore, the upper quartile is $6$ .
