Choose the correct answer from the options given below:

Correct option is B

Let's break down each of the types of projections and match them with the appropriate descriptions based on the correct order:
A. Oblique Projection: Oblique Projection is a type of projection where the object is projected at an angle. In this case, the angle between the projectors and the plane of projection is not 90°, and as a result, the lines perpendicular to the plane of projection are foreshortened.
· Correct Match: IV. When the angle between the projectors and the plane of projection is not equal to 90°.
B. Cavalier Projection: Cavalier Projection is a type of oblique projection where the projectors are angled such that there is no foreshortening of the object’s lines. In this case, the projection results in a view of the object where the lines are fully retained without reduction.
· Correct Match: II. When the direction of projection is so chosen that there is no foreshortening of lines perpendicular to the plane of projection.
C. Cabinet Projection: Cabinet Projection is also a type of oblique projection, but in this case, the lines are foreshortened by half their actual length to reduce the distortion in the final image. This type of projection is used to create a more realistic appearance.
· Correct Match: I. When the direction of projection is so chosen that the lines perpendicular to the plane of projection are foreshortened.
D. Orthographic Projection: Orthographic Projection is a method where the direction of projection is perpendicular to the plane of projection. This creates a true-to-scale, undistorted view of the object.
· Correct Match: III. When the direction of projection is perpendicular to the plane of projection.
The correct answer is: Option b: A-IV, B-II, C-I, D-III.
Information Booster:
1. Oblique Projection: In oblique projection, the object is projected at an angle other than 90°, causing lines to be foreshortened depending on the angle. This type of projection is useful for creating an angled view of an object.
2. Cavalier Projection: Cavalier Projection is a specific type of oblique projection where there is no foreshortening of the object. It is useful when the true proportions of the object need to be shown, but it does cause some visual distortion, especially in depth.
3. Cabinet Projection: Cabinet Projection also uses oblique projection, but the foreshortening factor is typically set to half the length of the actual object. This type of projection is often used in technical drawings because it provides a more visually realistic view compared to cavalier projection.
4. Orthographic Projection: In orthographic projection, the object is projected at a perpendicular angle to the plane, ensuring that the object appears undistorted. It is commonly used in engineering and architectural drawings to represent objects accurately.
Additional Knowledge:
· Oblique vs. Orthographic Projection: Oblique projections are used when a three-dimensional object needs to be displayed at an angle, with some distortion to show depth. Orthographic projections are used for accurate, undistorted views where dimensions are represented without perspective.
