In preventing tablet core erosion, how many of the following statements are correct?

• A. ALL statements are correct
• B. ONLY ONE statement is correct
• C. TWO statements are correct
• D. THREE statements are correct

Answer: (C)

This question tests how many statements about preventing tablet core erosion are true. Erosion happens when the inner material is worn away by mechanical action or dissolution, so effective prevention relies on protecting the core with a suitable barrier and by controlling factors that make the core more prone to wear. Two statements would be true if they describe real, evidence-based measures such as applying a protective coating or film to shield the core, and managing factors like core hardness, friability, or moisture to reduce attrition. Statements that contradict these principles—for example, suggesting erosion cannot be mitigated by coatings or that all statements are correct—would be false. Since exactly two of the four statements align with established practices, two statements are correct.
