Solution

The correct option is B Bones
Cartilage is a specialized type of dense connective tissue designed to give support, bear weight and withstand tension, torsion and bending.
In the vertebrate embryo, the greater part of the skeleton consists of cartilage, which is gradually replaced by bone during development.
Early in development, cartilage makes up most of the vertebrate skeleton. As an individual grows older, calcium deposits form around the skeleton, and bone eventually replaces most of the cartilage. This process is called ossification. Ossification begins in humans when the fetus is still in the womb and is not complete until early adulthood
Hence Most of the cartilages in the vertebrate embryo are replaced in the adult by bones.
So, the correct answer is 'Bones'.
