Which of the following is an example of a secondary need for customers?

A secondary need refers to wants or desires that enhance quality of life but are not essential for survival. In this case, using a radio outdoors in all types of weather fits this description perfectly. While it can provide enjoyment and enhance outdoor experiences, it is not a necessity for basic living.

On the other hand, the other options represent primary needs or essential goods and services. Buying a new car for transportation indicates a fundamental need for mobility and access, while purchasing food to satisfy hunger addresses a basic human requirement for sustenance. Arranging travel for a holiday is also more aligned with fulfilling a desire for leisure and enjoyment rather than satisfying a basic need. Therefore, using a radio outdoors is an example of a secondary need, as it is more about enhancing experiences rather than meeting essential requirements.
