Solution

The correct option is B lingual frenulum
The tongue is attached to the floor of the mouth by a folded structure called lingual frenulum. The main function of the lingual frenulum is it provides support to the tongue and also limits the movement of the tongue in different directions thus helping us while eating and speaking.

The anterior portion of the roof is called the hard palate. It consists of hard ridge-like structures called rugae.

The upper surface of the tongue consists of raised structures called papillae, many of which contain taste buds.
Tonsils are components of the Waldeyer’s ring. They consist of lymphoid tissue and act as the first line of defence against the microbes entering through the oral and nasal passage.
