**Core Concept**
Thalassemia major, also known as beta-thalassemia major, is a severe genetic disorder characterized by significant reduction or absence of beta-globin chains in hemoglobin, leading to severe anemia, bone deformities, and other complications.

**Why the Correct Answer is Right**
The correct answer is likely to be one of the options that do not describe a feature of thalassemia major. This condition is characterized by severe anemia, which requires regular blood transfusions, and bone deformities, such as skeletal dysplasia and osteoporosis, due to marrow expansion. Additionally, thalassemia major is associated with iron overload, which can lead to organ damage.

**Why Each Wrong Option is Incorrect**
**Option A:** This option might describe a common feature of thalassemia major, such as severe anemia or bone deformities.
**Option B:** This option might also describe a feature of thalassemia major, such as iron overload or frequent blood transfusions.
**Option C:** This option might be incorrect because it does not describe a feature of thalassemia major, or it might be a distractor that is actually a feature of a different condition.

**Clinical Pearl / High-Yield Fact**
Thalassemia major is often associated with significant morbidity and mortality if left untreated, but regular blood transfusions and iron chelation therapy can significantly improve quality of life and life expectancy.

**Correct Answer:** C.
