Which of the following is the best example of a company resource?

Proven technological expertise stands out as the best example of a company resource because it represents a specific asset that a company possesses which can be leveraged to gain a competitive advantage in the market. Resources are typically defined as the tangible and intangible assets that a firm controls, and technological expertise is a crucial intangible resource that can lead to innovation, improved efficiency, and the ability to produce unique products or services.

This expertise can contribute significantly to a firm's capabilities and overall strategic positioning. For example, a company with strong technological know-how can develop new products faster, respond to market changes more efficiently, and execute on strategic initiatives that leverage this expertise.

Looking at the other options, while higher earnings per share may indicate a company's financial success, it does not directly reflect a specific resource. Complete self-sufficiency without external partnerships may suggest a certain operational strategy, but it is not inherently a resource itself; companies frequently benefit from collaborations and partnerships. A greater number of competitive assets speaks to the scope of resources a company may possess, but it does not provide insight into the value or quality of those assets. Hence, proven technological expertise embodies a clear, actionable resource that drives growth and success in a competitive environment.
