The curve obtained by joining the points, whose x-coordinates are the upper limits of the class interval and y-coordinates are corresponding cumulative frequencies is called:
Ogive
An Ogive is a cumulative frequency curve obtained by plotting class limits on the x-axis against cumulative frequencies on the y-axis and joining the points. When upper class limits are used, the result is the less-than ogive; lower limits give the more-than ogive.
A histogram uses class intervals as bars with frequencies (not cumulative). A frequency polygon joins class mid-points against frequencies. A pie chart shows proportions of a whole, not class-wise cumulative frequencies. Hence the correct answer is Ogive.
