Asphyxia is primarily caused by what condition?

  1. An allergic reaction

  2. A bacterial infection

  3. A lack of oxygen due to difficulty breathing

  4. Exposure to toxic chemicals

The correct answer is: A lack of oxygen due to difficulty breathing

Asphyxia is a condition where the body is not receiving enough oxygen. While an allergic reaction, bacterial infection, and exposure to toxic chemicals can all cause difficulty breathing, they are not the primary cause of asphyxia. Asphyxia itself is a result of insufficient oxygen reaching the body's tissues, and can be caused by a variety of factors such as choking, drowning, or suffocation. Therefore, the lack of oxygen due to difficulty breathing is the most likely cause of asphyxia in most cases.
