The answer to this is C. Pre-tracheal Fascia. This is located in the neck area and this envelops the thyroid gland is enveloped in this fascia. It is one of the compartments responsible for protecting the trachea, larynx, pharynx, and esophagus.

Whenever a person swallows, this pre-tracheal fascia also moves along. This is known to assist in the formation of the carotid sheath. These are connected to some cartilages and to the pericardium. This is the reason why the thyroid glands move along whenever a person will swallow.

The Pretracheal fascia of the cervical fascia runs from the investing layers in both sides of the lateral neck and splits to enclose the thyroid gland. Superiorly, it attaches to the laryngeal cartilages; inferiorly, it fuses with the pericardium. as a result of these connections, the thyroid gland moves with laryngeal movements.
