Previous Year Question
Which of the following statements regarding the larynx is correct?
A.
It prevents pathogens from invading the trachea.
B.
It contains vocal cords.
C.
It is made of cartilage and connects the pharynx with the trachea.
D.
It is a bony box.
Correct Answer: C
Detailed Solution
The larynx is a cartilaginous part of the respiratory system. According to NCERT, the pharynx opens through the larynx region into the trachea, and the larynx is a cartilaginous box that helps in sound production. Therefore, option C is correct.
However, there is an important error in this question because option B is also scientifically correct. NCERT clearly states that the vocal cords are located inside the larynx or voice box, and their vibrations produce sound.
Therefore, according to answer key, C is the expected answer, but scientifically both B and C are correct statements.
