Step 1: Investor’s viewpoint.
An investor evaluates risk, profitability, and sustainability. High debt burden, lack of competitive edge, or weak strategy are red flags that discourage investment.
Step 2: Assess each option.
- (A) New entrants may offer better deals, but that does not necessarily make the merger unattractive by itself. ✗
- (B) Market competitiveness is always a factor, but by itself it is too generic — does not provide a strong reason to avoid investment. ✗
- (C) Absence of “grand strategies” is vague; investors look for concrete disadvantages rather than presentation style. ✗
- (D) Blaming opportunism of an individual (Mr. Das) is personal, not a solid financial reason. ✗
- (E) This highlights the most critical issue: LMN financed the merger with \emph{high-cost debt}, and the combined entity still faces the same structural problems as before. There is no new advantage, but higher liabilities, making this a strong reason to avoid investing. ✓
Step 3: Final conclusion.
Since the company now carries expensive debt while offering no competitive edge, investing is risky. Thus, option E is the strongest reason.
