The correct choice reflects the significant relationship between lower extremity deep venous thrombosis (DVT) and pulmonary embolism (PE). Studies indicate that a substantial majority of pulmonary emboli originate from DVT, primarily due to the prevalence of venous thrombi in the lower extremities. When a thrombus forms in the deep veins, particularly in the legs, fragments can break off and travel through the venous system to the right side of the heart and subsequently to the pulmonary arteries, leading to a PE.

Research consistently shows that the overwhelming majority of pulmonary emboli can be traced back to DVT, with estimates suggesting up to 90% or more. This understanding highlights the critical importance of early diagnosis and management of DVT to prevent the serious complication of pulmonary embolism. In clinical practice, recognizing the high association between these conditions is crucial for effective patient care and intervention strategies.
