A- it is not misleading

b - the x-axis does not have a consistent scale .

c - the axes are both labeled

Well, we can clearly see that both axises are labeled. The left axis (often called the y-axis) is labeled Scores and the bottom axis (often called the x-axis) is labeled Students.

The graph doesn't look to be misleading either.

As for the middle statement:
The x-axis doesn't need a scale.
The y-axis is clearly increasing in 5-point intervals.

So, the answer is B. Statement B is not true.
