How do bangles indicate that someone is becoming ill?

Bangles are often worn as cultural symbols in various societies, particularly in South Asian communities. In these contexts, the physical state of the bangles can hold significant meaning. When someone becomes ill, it is believed that the bangles may tarnish and leave a black ring on the skin. This observation serves as a sign or indication of deteriorating health. The tarnishing and formation of a black ring signify a change in the body’s condition, aligning with cultural beliefs surrounding health and well-being.

The other options do not carry the same cultural significance or have established meanings related to illness. While tightness or breaking might be seen as issues with the bangles themselves, they do not traditionally signify health changes in the same way that tarnishing does. Overall, the association between tarnishing bangles and health serves as a cultural indicator, making it the most appropriate answer in this context.
