What solid figure can have the same cross section as a sphere?
1) rectangular prism
2) pyramid
3) cube
4) cone

In order to visualise a cross-section of an object, imagine taking a very thin slice through its interior. When doing this with a sphere, the cross-section has the shape of a circle. When slicing a cone, the cross-section is also found to be a circle. The diameter of the circle decreases as one gets closer to the closed end of the cone. 

Bis the right answer

So confused right here i need it to be more clearer
