Which of the following best describes something that is 'sore'?

Describing something as 'sore' primarily refers to it being painful, particularly when touched or moved. This term is often used to characterize muscle pain resulting from overuse or injury, where any pressure or movement can lead to discomfort. When muscles are sore, they may feel tender to touch, indicating irritation or inflammation in the affected area. This definition is consistent with how soreness is commonly understood in both casual language and medical terminology, reinforcing the correctness of the chosen answer.

In contrast, the other choices provide interpretations that deviate from the meaning of soreness. A lack of pain and discomfort is the opposite of being sore, while a feeling of complete relaxation suggests a state of comfort rather than pain. Similarly, describing something as a mild annoyance does not capture the physical and painful experience associated with being sore. Thus, the selection accurately reflects the defining characteristics of soreness.
