The correct answer is A

Traditional evaluation of PE begins with the ventilation-perfusion (V/Q) scan, which is considered the pivotal diagnostic test. Unfortunately, the test results are often nondiagnostic.

Previously, most patients with low- or intermediate-probability V/Q scans and clinical suspicion for PE would undergo pulmonary angiography, which remains the gold standard for ruling out PE.
