Explanation:

• Epiphyseal cartilages fuse to form epiphyseal line during growth, which is a normal skeletal development process from birth to young adulthood.
• Fontanelles, the soft - spots on a baby's skull, close as the skull bones grow and fuse.
• The major curves of the vertebral column develop as a child learns to lift its head, sit, and stand. The mineral content of the bony matrix increases during growth, not decreases.

Answer:

A. Fusion of the epiphyseal cartilages to form epiphyseal line
C. Closure of the fontanelles
D. Development of the major curves of the vertebral column
