• B. Palate
• C. Vulva
• D. None of these

Answer 1

The correct option is B

Palate

The correct option is B.

Explanation for the correct option:

1. The lining of the mouth's roof. The front part (hard palate) is bony, whereas the rear part is muscular (soft palate).
2. The roof of the mouth is made up of soft and hard palates.
3. The soft palate is located in the rear of the roof, whereas the hard palate is located closer to the teeth.
4. The soft palate's primary roles are to facilitate speaking, swallowing, and breathing.

Explanation for the incorrect options:

Option A

1. The palatine bone is a paired, L-shaped facial bone that makes up a section of the nasal cavity and palate.
2. It is located between the maxilla bone (the fixed upper jaw bone) and the sphenoid bone on the bottom of the head (whose wings help form the base of the eye sockets and base of the skull).

Option C

1. The vulva, which includes the labia majora, minora, and clitoris, is the outer region of the female genitalia.
2. The vulva's main duties are to protect the internal organs of the female reproductive system (labia majora and minora), as well as to contribute to sexual pleasure and stimulation (clitoris) to enhance intercourse, such as by supplying lubricant and cushioning (Bartholin's glands) (mons pubis).

Final answer: Nasal chambers and buccal cavity are separated by the palate.
