The description of the distribution suggests that it is positively skewed, meaning that the tail of the distribution extends to the right and there are fewer high values than low values. This is consistent with the fact that most salaries are lower and there are fewer people with high salaries. A normal bell-shaped curve (A) would imply that salaries are distributed evenly around a central value, which is not the case here. Negatively skewed (B) would imply that the tail of the distribution extends to the left, which is not what we would expect for salaries. Mesokurtic (D) refers to the shape of the distribution's peak or center, which is not the issue being described here.
