The correct answer is A. Annual CT scan. The US Preventive Services Task Force recommends annual screening with low-dose computed tomography (CT) for individuals aged 55-74 years who have a 30 pack-year smoking history and currently smoke or have quit within the past 15 years. This recommendation aims to detect lung cancer at an earlier, more treatable stage and reduce mortality associated with lung cancer.

Options B, C, and D are not recommended lung cancer screening methods for individuals aged 55-74. X-rays every 2 years do not have sufficient sensitivity or specificity for detecting lung cancer in high-risk individuals. MRI annually is not the recommended screening modality for lung cancer in this age group. Biopsy is an invasive procedure that is not used for screening purposes in asymptomatic individuals.
