Answer:
D. Both have quality standards.
Step-by-step explanation:
Gods are tangible, homogeneous, stored & ownership transferable material things, whose production & consumption occur at different point of times.
Services are intangible & immaterial, heterogeneous, that can't be stored or ownership transferred, whose production & consumption occur at same point of time.
Goods Eg: Clothes, Services eg : Teaching
Mass production can happen with more degree in goods & services, rather than services rendering. Consistency (homogeneity) & inventory stock (storage), as mentioned - are features more related to goods than services.
However, both goods & services have quality standards. Quality standards are requirements & specified characteristics denoting fitness of them to their real purpose.
Eg: Both clothes production & teaching service rendering have quality standards
