- CA-I, B-III, C-II, D-IV
- DA-III, B-IV, C-I, D-II
Solution
Mesethmoid cartilage forms the nasal septum, which divides the nasal cavity into right and left chambers. Thus, A matches with II.
'C' shaped incomplete cartilaginous rings are present in the trachea to prevent it from collapsing during inspiration. Thus, B matches with IV.
Epiglottis is a cartilaginous flap that covers the glottis and prevents the entry of food into the trachea during swallowing. Thus, C matches with III.
Diaphragm is a dome-shaped muscular structure that separates the thoracic cavity from the abdominal cavity. Thus, D matches with I.
The correct matching is A-II, B-IV, C-III, D-I.
Answer: A-II, B-IV, C-III, D-I
'C' shaped incomplete cartilaginous rings are present in the trachea to prevent it from collapsing during inspiration. Thus, B matches with IV.
Epiglottis is a cartilaginous flap that covers the glottis and prevents the entry of food into the trachea during swallowing. Thus, C matches with III.
Diaphragm is a dome-shaped muscular structure that separates the thoracic cavity from the abdominal cavity. Thus, D matches with I.
The correct matching is A-II, B-IV, C-III, D-I.
Answer: A-II, B-IV, C-III, D-I
Hence, the correct answer is option: 'B'.
