In the shape analogy "Spring : spiral :: bangle : ____", which option best describes the geometric shape of a bangle?

Introduction / Context:
This analogy checks whether you can recognise the relationship between an object and its characteristic shape. In the pair "Spring : spiral", the second word describes the typical geometric form of a spring. You must find a similar description for a bangle. These kinds of questions appear regularly in reasoning tests to check conceptual understanding of everyday objects and basic geometry.

Given Data / Assumptions:

• A spring is commonly coiled in a spiral shape.
• A bangle is a circular ornament worn around the wrist.
• Options include material related words and general categories as distractors.
• The pattern is "object : its typical shape".

Concept / Approach:
In the first pair, spring is not being described by material or by use; it is described by its physical form, which is spiral. Therefore, for the second pair we should also describe the physical form of a bangle. A standard bangle is round, forming a loop that can slide over the hand and rest on the wrist. This shape is best described as a circle. The other options like glass, ornament and gold refer to material or category, not to shape, so they do not parallel the relationship in the first pair.

Step-by-Step Solution:

Identify that spiral describes the geometric form of a spring. Recognise the pattern "object : its usual shape". Recall that a bangle is usually a closed loop worn around the wrist. Note that this loop is circular when viewed from the front, which matches the term circle. Confirm that circle is the only option that names a shape rather than a material or broad category.

Verification / Alternative check:
Glass and gold describe possible materials from which a bangle can be made, but they do not express its shape. Ornament is a general term for decorative items and also does not identify geometry. Spiral is already used to describe the shape of a spring and does not fit a typical bangle, which is not coiled. Hence none of these match the precise relationship between spring and spiral. Only circle expresses the same geometric kind of information that spiral does in the first pair.

Why Other Options Are Wrong:
Choosing glass, gold or ornament changes the relationship from shape based to material or category based. That would no longer mirror the relationship between spring and spiral. Analogy questions demand that the type of relationship remain consistent across both pairs, so these options are incorrect.

Common Pitfalls:
A frequent mistake is to focus on what a bangle is made of or how it is used, instead of how it looks geometrically. Another pitfall is to be attracted to the word ornament, because a bangle is indeed an ornament, but that does not match the shape focus of the first pair. Always check whether you are comparing the same property in both parts of an analogy.

Final Answer:
The pair that mirrors "Spring : spiral" is "Bangle : circle".
