Explanation:

To understand why the correct answer is option 'B' (cuboid), let's first define the terms and properties of each option:

1. Cube: A cube is a three-dimensional shape with six equal square faces. All edges of a cube are of the same length, and all angles are right angles.

2. Cuboid: A cuboid is a three-dimensional shape with six rectangular faces. Unlike a cube, the lengths of the edges can be different, but opposite faces are always congruent and parallel.

3. Cylinder: A cylinder is a three-dimensional shape with two parallel circular bases and a curved surface connecting the bases. It does not have any rectangular faces.

4. Cone: A cone is a three-dimensional shape with a circular base and a curved surface tapering to a point called the apex. It does not have any rectangular faces.

Extrusion:
Extrusion is a process of extending a shape along a specific direction to create a new solid shape. In this case, a rectangle is being extruded out of its plane, which means it is being extended in a direction perpendicular to the plane of the rectangle.

Analysis of options:
Based on the definitions and properties mentioned above, we can eliminate options 'A' (cube), 'C' (cylinder), and 'D' (cone) as they do not involve extrusion of a rectangle.

However, option 'B' (cuboid) fits the description perfectly. When a rectangle is extruded out of its plane, it creates a solid shape with six rectangular faces. The extruded rectangle becomes the top and bottom face of the cuboid, while the remaining four sides are also rectangular.

Thus, the correct answer is option 'B' (cuboid), as it is the only shape that matches the process of extruding a rectangle out of its plane.

Cuboid is obtained from extruding rectangle
