Options

  1. AA-II, B-III, C-IV, D-I
  2. BA-II, B-IV, C-III, D-I
  3. CA-I, B-III, C-II, D-IV
  4. DA-III, B-IV, C-I, D-II

Correct answer

B. A-II, B-IV, C-III, D-I

Step-by-step 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.
