The correct option is: B. 11
Explanation
In the given scatter plot, the number of computers are shown across the y-axis.
Only one point is lying on the line y=6 and all other points are above that y=6 line. That means, only 1 office had 6 computers.
As there were total 12 different offices, so the number of offices that had more than 6 computers will be: (12 - 1) = 11
