The correct option is
A We have to identify which of the given nets is not correct for a cylindrical shape.
As we know, a cylinder is a 3D shape that has two circular parallel faces connected by a curved surface.
On a net of the cylinder, the curved surface can be rolled out to reveal a rectangle.
So, after analyzing these properties of a cylinder, we can say that except the last option, all the given nets have circles of the same radius.
Since, the fourth option does not have circles with the same radii, it cannot take a shape of a cylinder.
Hence, option (d) is the correct option.
