Question

Which of the objects shown in the options form(s) a perfect circle?

• A. A
• B. B
• C. C
• D. D

Hint:

For questions about geometric patterns, pay close attention to the wording. "Forms a perfect circle" likely refers to the overall boundary or outline of the collective shape, not just the placement of the individual elements' centers. Look for smooth, continuous curves versus jagged, polygonal outlines.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
The question asks which of the four types of objects, when arranged as shown in the main image, forms a perfect circle. The options A, B, C, and D correspond to the individual shapes: A (white octagon - although in the diagram they are circles), B (teal crescent), C (pink pentagon), and D (green square). We must inspect the rings formed by each type of object in the main diagram and determine which ring has an outline that is a perfect circle.

Step 2: Detailed Explanation:
Let's analyze the circular patterns formed by each set of shapes, from the inside out.

Innermost Ring (White Circles): This ring is composed of individual white circles. While their centers lie on a perfect circle, the overall boundary of the ring is scalloped due to the gaps between the circles. It does not form a solid, perfect circle.

Second Ring (Green Squares - D): This ring is made of green squares. The inner and outer boundaries of this ring are jagged, following the straight edges of the squares. It is not a perfect circle.
Third Ring (Pink Pentagons - C): Similar to the squares, this ring is composed of pentagons. Its inner and outer boundaries are polygonal and not smooth circles.
Outermost Ring (Teal Crescents - B): This ring is made of crescent-shaped objects. These objects are designed to fit together perfectly along a circular path. Their inner boundary forms a perfect circle, and critically, their outer boundary also forms a continuous, smooth, perfect circle.

Step 3: Final Answer:
The arrangement of the teal crescent objects (labeled B in the options) is the only one that results in a pattern with a perfect circular outer boundary.
