D is wrong here so correct option for the given question is (D). Kindly look at the images below for detailed solution I've attached for clarification. Kindly ask me in case of any doubt. In case of tetragonal dipyramid you can easily observe that it is a closed form and bounded by the symmetrical pyramids. 2nd image is of Ditetragonal pyramidal class 3rd image is of Tetragonal dipyramidal class... Clearly look at the structure it is self explanatory.
