Computed Tomography CT is the correct answer because it uses a rotating X-ray source to capture multiple images of an object from different angles, creating a detailed three-dimensional view. This technology uniquely calculates a material's mass, density, and mass absorption coefficient, making it highly effective for detecting explosives and other threats. In organizational and Human Resource related security management, advanced screening technologies like CT scanners are essential for ensuring workplace safety, especially in high-risk environments such as airports, government facilities, and corporate offices. These systems support security personnel by providing accurate threat identification, reducing human error, and improving decision- making. Other technologies like standard X-ray or backscatter systems do not provide the same level of detailed material analysis. Therefore, option B is correct because CT offers the most comprehensive detection capability.
