A second-degree quadriceps strain is characterized by a partial tear of the muscle fibers, which leads to specific clinical manifestations. Pain during activity is a hallmark symptom, as the damaged muscle struggles to perform its usual function effectively. The strain compromises the muscle's capacity, resulting in decreased range of motion (ROM) and overall function as the individual may avoid certain movements that provoke pain.

In this context, the presence of pain during activity alongside a notable decrease in range of motion and functional ability aligns directly with the common presentations of a second-degree muscle strain. This level of strain typically also involves some degree of swelling and tenderness, further contributing to the limitations in movement and usage of the affected muscle.

The other options do not accurately reflect the nature of a second-degree strain. For instance, complete tears describe a third-degree strain, while a lack of pain with movement is not characteristic of a second-degree strain, as pain is a significant symptom in such injuries. Minimal loss of strength with tenderness would be more indicative of a first-degree strain, which typically involves less severe damage. Therefore, the description of pain during activity and decreased ROM and function distinctly encapsulates the features of a second-degree quadriceps strain.
