Which one of these factors may influence the success rate of a merger?

A) stress counselling for employees
B) industry sector of the merger
C) both companies being the same size
D) languages spoken by management

The industry sector of the merger can greatly influence the success rate as the compatibility and synergy between the two companies may differ based on the nature of the industry. For example, a merger between two companies in completely different industries may have more challenges than a merger between two companies in related industries. The other options listed may not have a strong influence on the success rate of a merger.
