I have attached a picture of the double cone.
I have also attached the options missing.
Answer:
Option B is correct
Step-by-step explanation:
From the image of the double given, when we cut a section vertically through the centre where the tips of the cones meet, when we look at the cut section, we will not see curves but straight lines meaning that the top and bottom will be horizontal lines and not curves.
Also, the meeting point of the two cone tips will remain the same.
Looking at the options, the only one that fulfills the condition is option B.
