Step 1: Identify the Core Issue
Biswas resents teachers’ influence and is searching for an opportunity to justify reducing their salaries. However, the justification must not appear personal — it must be supported by strong external factors that would convince the trustees.
Step 2: Analyze the Options
- (A) Teachers’ demands → does not justify salary reduction, only refusal of increment.
- (B) Enrollment fall → partially valid, but trustees will focus on how to improve admissions, not cut teachers’ salaries.
- (C) Competing schools paying less → weak argument; trustees prefer retaining talent.
- (D) Budget deficit → general reason, but not specific enough to justify a 20% reduction in salaries.
- (E) Parent complaints about high fees → strong justification, as trustees would prioritize keeping parents satisfied and ensuring financial sustainability.
Step 3: Logical Justification
The strongest case Biswas can present is that parents are demanding cost-cutting. Trustees are directly accountable to parents (since they pay the fees). Thus, aligning salary reduction with parent concerns provides the most persuasive argument.
Step 4: Conclusion
The BEST enabling factor for Biswas’s proposal is option (E): parent complaints about high fees and the need to cut costs.
Final Answer:
\[ \boxed{\text{Parents have begun complaining about high fees and demand cost-cutting.}} \]
