Answer:
Correct Answer: C
Solution:
Pinna is made of elastic cartilage containing elastic fibres between scattered chondroctes.
The elastic fibres make it considerably elastic in nature.
In hyaline cartilage, the matrix is fibreless and glass like.
It forms the initial skeleton of the foetus.
In adult, it is found in bronchi, larynx, nasal septum, branchial rings etc., It gives mechanical support.
