Answer: (B)

Verified step by step guidance

1. Step 1: Understand the context of mergers and acquisitions (M&A). M&A failures often occur due to various challenges that arise during or after the merger process.
2. Step 2: Identify common reasons for M&A failures. These typically include poor integration of company cultures, overestimation of synergies (expecting more benefits than realistically achievable), and regulatory challenges such as high post-merger Herfindahl-Hirschman Index (HHI), which measures market concentration and can lead to antitrust issues.
3. Step 3: Analyze the option 'Effective communication between merging firms.' Effective communication is generally considered a positive factor that facilitates successful integration and reduces misunderstandings.
4. Step 4: Compare the options to determine which one does NOT contribute to failure. Since poor integration, overestimation of synergies, and regulatory challenges are known failure reasons, the option that is a positive factor (effective communication) is the one that does NOT cause failure.
5. Step 5: Conclude that 'Effective communication between merging firms' is NOT a reason for merger and acquisition failures because it helps prevent problems rather than causing them.
