Percolation is a method of preparing syrups which involves passing distilled water or medicated component slowly through a bed of sucrose. Which of the following are correct?

• A. ALL statements are correct
• B. ONE of the statements is correct
• C. THREE of the statements are correct
• D. TWO of the statements are correct

Answer: (D)

Percolation in syrup preparation relies on slowly passing a solvent through a bed of sucrose that contains the medicated material, so the drug is extracted and distributed evenly into the syrup. The two statements that typically hold true about this method are: the solvent is passed through the bed slowly to ensure complete extraction and uniformity, and the bed of sucrose acts as the solid matrix that supports the percolation and helps form a homogeneous syrup as the liquid passes through. Because these two aspects capture the essential mechanism—controlled flow for thorough extraction and the sugar matrix providing the syrup with uniform distribution—the correct answer reflects that two statements are correct. The other options conflict with how percolation operates (for example, implying all statements are correct or that only one or three statements are true).
