Disregarding the budget constraints, which among the three plans satisfy all the guidelines laid down by the school administration?
Evaluating each of the guidelines: Capacity of at least 1,800 students: Plan A: 1,800 students (Meets the requirement) Plan B: 2,000 students (Meets the requirement) Plan C: 2,000 students (Meets the requirement) At least one study room for every 50 students: Plan A: 1,800 students, requires 1,800 ÷ 50 = 36 study rooms. Plan A has 36 study rooms (Meets the requirement). Plan B: 2,000 students, requires 2,000 ÷ 50 = 40 study rooms. Plan B has 50 study rooms (Exceeds the requirement). Plan C: 2,000 students, requires 2,000 ÷ 50 = 40 study rooms. Plan C has 38 study rooms (Does not meet the requirement). At least 80 faculty offices: Plan A: 80 faculty offices (Meets the requirement) Plan B: 85 faculty offices (Meets the requirement) Plan C: 90 faculty offices (Meets the requirement) At least 40% of the total area must be designated as open space: Plan A: 40% open area (Meets the requirement) Plan B: 40% open area (Meets the requirement) Plan C: 40% open area (Meets the requirement) Plan A: Meets all the guidelines. Plan B: Meets all the guidelines. Plan C: Fails to meet the study room requirement (does not have 40 study rooms). Thus, the plans that satisfy all the guidelines are Plan A and Plan B.

Corrected Answers:
