In equine terminology, "grabbing his quarters" refers to a horse's tendency to injure or interfere with its own legs, particularly by striking its own hoof with its opposite leg. This often happens when a horse overreaches, which is when the hind foot extends too far forward and strikes the front foot, usually referring to the horse’s quarters, or the area around the hoof. This action can lead to various injuries, including cuts, bruises, or more serious damage.

Overreaching is particularly relevant here, as it describes the action of the horse coming too close to or hitting its quarters, thereby tying the term directly to the phrase in question. The other options, while they reference different issues or conditions associated with horses and their legs, do not specifically correlate with the action of "grabbing his quarters." For example, 'popped knee' refers to a knee injury, 'quarter crack' is a condition related to cracks in the hoof wall, and 'monorchid' relates to a male horse with only one testicle.
