Defining design types
Step 1: In decorative arts, designs are typically categorized by their placement or function in a composition.
Listing design types
Step 2: The main types of design in this context are:
- Centre design (for focal points)
- Corner design (for edges or corners)
- Border design (for perimeters)
Thus, there are three primary types.
Evaluating options
Step 3: Analyze the options:
- (A) 2: Incorrect, as it undercounts the types.
- (B) 3: Correct, matching centre, corner, and border designs.
- (C) 4: Incorrect, as no standard fourth type is typically defined.
- (D) 5: Incorrect, as it exceeds standard categories.
Thus, the correct answer is (B).
