The correct answer is B. kitchen E. patient room. MRI scans emit at a frequency of 1MHz-300MHz, which is below the frequency of Wi-Fi (2.4GHz and 5GHz). Gamma rays (Exahertz) and X-rays (Petahertz) are happening at frequencies much higher than RF as well. Kitchens can be source of 2.4GHz interference with microwave ovens…

Explanation
MRI scans emit at a frequency of 1MHz-300MHz, which is below the frequency of Wi-Fi (2.4GHz and 5GHz). Gamma rays (Exahertz) and X-rays (Petahertz) are happening at frequencies much higher than RF as well. Kitchens can be source of 2.4GHz interference with microwave ovens. People have mobile devices in patient rooms such as tablets and cellphones which adds to the rf noise on 2.4Ghz and 5Ghz.
