Difficulty: Easy
Correct Answer: Plate
Explanation:
Introduction / Context:
Shape-based classification is a robust method in reasoning questions. Here, three options are circular with a central hole facilitating wearing, mounting, or rotation, while one is a solid disc without a through-hole. The presence or absence of a hole is an objective geometric discriminator.
Given Data / Assumptions:
Concept / Approach:
Group by topology: torus-like objects with a central aperture versus a solid disc. The functional design of ring, tyre, and bangle depends on the hole; a plate does not share that property.
Step-by-Step Solution:
Verification / Alternative check:
Consider usage: the hole enables wearing or mounting; plates serve as surfaces, not mounts.
Why Other Options Are Wrong:
They all belong to the hollow circular class with an essential central opening.
Common Pitfalls:
Do not be misled by materials or size; the decisive feature is the presence of a through-hole.
Final Answer:
Plate
