Answer:
Shape 2
Step-by-step explanation:
We are given a cylindrical shell with its axis of rotation.
It is given that a plane passes through its axis of rotation.
Now, as we can see that when a plane passes through the axis of rotation, which is vertical, we will obtain a cross-sectional area resembling rectangular planes.
Hence, the cross-sectional area obtained according to our question will be shape 2 depending on the plane passing through the cylindrical shell.
