An example of synergy in business is:

The example of synergy in business represented by the merger of JP Morgan Chase and Bank One Corporation highlights how two companies can combine their strengths to create a more powerful entity. In this case, the merger allowed JP Morgan to gain access to Bank One's extensive network of retail branches in new geographic areas, enhancing its market presence and operational capabilities.

This synergistic effect occurs when the combined value and performance of the merged entities exceed the sum of their individual parts. By integrating resources, talents, and customer bases, JP Morgan was able to improve efficiency, expand its customer reach, and potentially increase profitability more effectively than either company could achieve alone. This exemplifies how strategic partnerships or mergers in business aim for enhanced capabilities and competitive advantages that would not be possible independently.

Other choices may illustrate important business strategies, but they do not capture the essence of synergy as effectively as the merger option does.
