Final answer:
The definition of credence quality is attributes of a product or service that cannot be easily assessed by consumers even after consumption, requiring trust or specialized knowledge to evaluate.
Step-by-step explanation:
Credence quality refers to aspects of a product or service that cannot be evaluated by customers even after consumption. This type of quality is inherent in services that require a high level of trust or specialized knowledge to assess, such as medical procedures or legal advice. For example, a patient may not be able to accurately assess the technical quality of a heart surgery but would have to rely on the credentials and reputation of the surgeon and hospital.
Thus, when answering a question about the definition of credence quality in the context of product or service quality, the correct choice would be: (b) Quality known after consumption. This is not entirely exact as credence qualities are attributes that customers may find difficult to evaluate even post-consumption. The more accurate definition would align with qualities that consumers have difficulty assessing accurately due to their nature, which requires specialized knowledge or expertise to evaluate.
