What is a potential biological impact of exposure to extremely low frequency (ELF) electromagnetic fields?

Cataracts of lens
Electrostimulation
Thermal skin burns
Retinal burns

The correct answer is: Electrostimulation

ELF electromagnetic fields are non-ionizing radiation that is emitted from many electronic devices, such as power lines, cell phones, and radars. While some people may experience various health symptoms from direct exposure to ELF fields, including visual disturbances, the majority of scientific research does not support the notion that ELF fields cause harm to the human body. The incorrect options A, C, and D all suggest possible negative biological impacts of ELF exposure, but these have not been proven by scientific studies. Cataracts of the lens or thermal skin burns are more commonly associated with exposure to higher frequency radiation, while retinal burns are typically caused by thermal or chemical injuries. Therefore, the only potential biological impact of exposure to ELF electromagnetic fields is electrostimulation, which may cause tingling or burning sensations on the skin but is not considered harmful.
