  • red patches on their skin
  • loss of muscle mass

What is the likely condition that this person has?

A. iron deficiency
B. kwashiorkor
C. marasmus
D. scurvy

▶️ Answer/Explanation
Kwashiorkor is a protein deficiency disease that classically causes a swollen abdomen due to fluid retention, skin rashes/patches, and muscle wasting.
Marasmus, by contrast, causes overall severe wasting without the swollen belly, and iron deficiency or scurvy produce different symptoms (anaemia, or bleeding gums respectively).
The combination of symptoms described matches kwashiorkor specifically.
✅ Answer: (B)
