The correct answer is B. The Bureau of Civil Aviation Security (BCAS), India’s aviation security regulator, primarily mandates the use of Millimeter-wave (MMW) technology for full body scanners at airports.

BCAS has issued guidelines specifying MMW technology as the standard for body scanners. This technology uses non-ionizing electromagnetic radiation, which is considered safe for passenger screening.

While Back Scatter Technology exists and uses ionizing radiation (X-rays), it is generally not preferred for widespread passenger screening in India due to potential health concerns and is often not the technology prescribed by BCAS for new installations compared to MMW technology. Therefore, only MMW is the technology prescribed for mandatory installation.
