Which area is emphasized by GMP guidelines?

• A. Marketing campaigns
• B. Financial auditing
• C. Customer support
• D. Maintenance and infrastructure cleanliness

Answer: (D)

GMP guidelines focus on preventing contamination by controlling the production environment, equipment, and processes. Maintaining and cleaning the facility and infrastructure is essential because it directly protects product safety and quality—clean floors, walls, drains, proper waste handling, and well-maintained equipment all reduce the risk of contamination and cross-contact. Regular cleaning, sanitation, and preventative maintenance ensure the site remains sanitary, compliant with standards, and capable of producing consistent, safe products. The other options relate to business activities outside the production environment—marketing, financial auditing, and customer support—so they don’t address the control of cleanliness and maintenance that GMP emphasizes.
