The correct answer is C. Socks : Feet.
A glove is a covering for the hand, typically made of leather or cloth and having separate parts for each finger. A collar is the part of a shirt or coat that fits around the neck. A tie is a piece of cloth worn around the neck, typically with a knot at the front. Socks are a covering for the foot, typically made of wool or cotton. A coat is a long, loose outer garment, typically with sleeves and a collar. A pocket is a small opening in a garment or bag, used for storing things.
The relationship between a glove and a hand is similar to the relationship between socks and feet. Both gloves and socks are coverings for the extremities of the body, and both are typically made of soft, comfortable materials. Additionally, both gloves and socks can be used to protect the hands and feet from the elements, such as cold weather or rough surfaces.
The other options are incorrect because they do not have the same relationship as gloves and hands. A neck is not a covering for the head, and a collar is not a covering for the neck. A tie is not a covering for the head, and a shirt is not a covering for the neck. A coat is not a covering for the head, and a pocket is not a covering for the coat.
