Answer: C: Maternal acute puerperal mastitis 
Explanation: Ans. C. Maternal acute puerperal mastitisa. There are very few contraindications to breast-feeding. In acute viral infections, such as hepatitis B, there is the possibility of transmitting the virus in the milk.b. Most medications taken by the mother enter into breast milk, usually in concentrations similar to or less than those in maternal plasma.c. Breast-feeding is inadvisable when the mother is being treated with antimitotic drugs, tetracyclines, diagnostic or therapeutic radioactive substances, or lithium carbonate.d. Acute puerperal mastitis may be managed quite successfully while the mother continues to breast-feed. Reduction mammoplasty with auto- transplantation of the nipple simply makes breast-feeding impossible.
