Final answer:
Option a (flat-pack furniture marketed as inexpensive and easily portable) does not illustrate segmenting by age because it does not specify an age group.
Step-by-step explanation:
Segmenting by age involves tailoring products or services to specific age groups. Among the given options:
- Option a: Flat-pack furniture is marketed as inexpensive and easily portable – This does not specify an age group, therefore does not illustrate segmenting by age.
- Option b: A car is marketed with the tag "For their first car, pick a brand first in safety ratings." – This implies a younger demographic typically looking for their first car, which does indicate age segmentation.
- Option c: Breakfast cereal is marketed as being high in antioxidants, which have antiaging properties – This might appeal to older consumers concerned about aging, which suggests age segmentation.
- Option d: A miniature version of a well-known bicycle is marketed with three wheels – This is geared towards young children learning to ride, hence is age segmented.
The correct answer is Option a, as flat-pack furniture's inexpensive and portable nature does not specify an age group, making it not an example of segmenting by age.
