i dont know yet

Explanation:

Marfan's syndrome is a genetic disorder affecting the connective - tissue. It causes excessive cartilage formation at epiphyseal cartilages, leading to long and slender limbs. Gigantism is due to over - production of growth hormone, not specifically related to excessive cartilage at epiphyseal cartilages in the same way. Osteomalacia is a softening of the bones due to vitamin D or calcium deficiency. Achondroplasia is a form of dwarfism with abnormal cartilage and bone development but not characterized by long and slender limbs.

Answer:

Marfan's syndrome
