Which environment affects all businesses that provide similar products and services?

The industry environment is the correct choice because it encompasses the competitive landscape in which businesses operate, including the factors that directly influence organizations providing similar products and services. This environment is shaped by various elements such as the number of competitors, the level of industry growth, customer expectations, and the availability of substitutes. These elements collectively determine how companies within the same industry interact and strategically position themselves against each other.

In contrast, the internal environment refers to the specific resources, capabilities, and processes within an individual organization, which do not directly affect other businesses in the same sector. The product environment pertains more to the specific characteristics of a product and how it meets customer needs, while the remote environment covers broader external factors such as economic, political, and social influences that may not impact all businesses uniformly. Hence, the industry environment is fundamental in understanding how similar businesses operate and compete.
