All the options are correct.
If we look at the formula of prismoidal, we can see that it contains, three areas = area of faces at top and bottom and area of midway section
Thus it can be used to calculate the a) calculate surface area for cylindrical rings And b) estimate the surface area of edged non-prismoidal solids.
In the volume formula of prismoidal, the factor (depth/6) is multiplied by the three areas as mentioned above, this gives the volume of faces at top and bottom and midway section. Thus option C and D are also correct.
