All of the following are required resources for differentiation except: Strong marketing capability. Corporate reputation for quality. Product engineering. Intense supervision of labor.

For comprehension purpose, I would attach options to the question:

All of the following are required resources for differentiation except:

A. Strong marketing capability B. Corporate reputation for quality. C. Product engineering. D. Intense supervision of labor.

The correct answer is Option D (Intense supervision of labor)

Explanation:

The differentiation asked in the question above is product differentiation.

Product differentiation, in Economics, talks about the efficient way a producer or seller of a product makes it unique in the market thereby creating an edge between the product and other similar ones or other products.

So, strong marketing capability exposes the strength and uniqueness of the product to prospective buyers which in turn brings sales.

Corporate reputation and product engineering are a strong boost in sales, as reputable companies and the physical appearance of a product tend to get easy acceptance in the market. While Intense supervision of labor may increase the efficiency of production but it is not to be considered as a resource for differentiation.
