Answer:
The correct answer is letter "E": The primary rationale for most operating mergers is synergy.
Explanation:
A merger is usually the fusion of two firms by mutual consent. Two firms partner in mergers to create an entirely new entity. Mergers happen in a variety of forms and for a variety of reasons. There are horizontal mergers (two equal competitors who look forward to reducing costs) and vertical mergers (a company merging with a supplier).
Mergers are based on synergy since the purpose of the collusion is nothing more than producing a combined greater effect by two companies working together.
