Find the odd shape/object (spherical vs ring): Choose the option that is not spherical/globular but a circular band.

Introduction / Context:
Shape and topology provide reliable classification criteria. Spherical (or near-spherical) objects have roughly equal dimensions in all directions and enclose volume with no edges. A bangle, however, is a ring-shaped band (topologically a torus-like loop) rather than a sphere. This geometric difference yields a clear odd-one-out.

Given Data / Assumptions:

• Earth: approximately spherical (oblate spheroid) celestial body.
• Moon: approximately spherical natural satellite.
• Football: in common (association football) usage, a near-sphere ball; used on the field of play.
• Bangle: a rigid circular band with a central hole; not a sphere.

Concept / Approach:
Group by 3D shape class: sphere vs ring. Three items are spherical/near-spherical solids; one is a hollow circular band. The difference is categorical: a sphere has no hole and encloses volume uniformly; a ring has a central aperture and different geometry.

Step-by-Step Solution:

Verification / Alternative check:
Consider physical handling: balls roll as spheres; bangles slip over wrists due to the hole—distinct behaviors from spheres.

Why Other Options Are Wrong:
They share the same gross spherical geometry in everyday understanding.

Common Pitfalls:
Do not confuse “American football” (prolate spheroid) with association football; standard reasoning items intend the spherical soccer ball.

Final Answer:
Bangle
