Answer:
Option C is correct.i.e., we get Parabola if a cone is cut parallel to its edge.
Step-by-step explanation:
Given: A Right Circular Cone
To find: Shape of of cross section when cone is cut by a plan parallel
to edge of cone
Cone has an apex on top and circle in base so if it is cut parallel to its edge we get a shape which is curved or pointy on one end while on the other end it is open due to circle.
Option A: Circle is closed from everywhere,
Thus it is not correct.
Option B: Ellipse is also not open from any end.
Thus, it is not correct.
Option C: Parabola is curved from one end and open from other end.
Thus this is correct.
Option D: We get parabola if cone is cur parallel to axis.
Thus it is also not correct.
Therefore, Option C is correct.i.e., we get Parabola if a cone is cut parallel to its edge.
