This analogy question requires us to identify the relationship between the first pair of words and apply it to the second. The pair Hand: Glove establishes a relationship where a glove is an item of clothing worn directly on the hand, often as a close-fitting covering or first layer for protection or warmth.
Applying this same relationship to Foot: ?, we need to find an item of clothing that is worn directly on the foot in a similar close-fitting manner. A Sock perfectly fits this description, serving as a direct, form-fitting covering for the foot, analogous to how a glove covers a hand. Options B (Shoe), C (Slipper), and D (Sandal) are incorrect because while they are all types of footwear, they are typically worn over a sock or are outer coverings, not the direct, form-fitting layer that a glove or sock represents.
