Which symptoms are associated with asphyxiation?

The symptoms associated with asphyxiation primarily stem from the body's insufficient oxygen supply, leading to neurological and physiological distress. The symptoms listed include headache, drowsiness, dizziness, and nausea, all of which are common indicators of a deficiency in oxygen.

Headaches can occur due to changes in blood oxygen levels, while drowsiness and dizziness are often signs that the brain is not receiving adequate oxygen. Nausea can also be a consequence of the stress that low oxygen levels put on the body. These symptoms collectively indicate that the individual's body is struggling to maintain proper respiratory function and overall homeostasis, which is characteristic of asphyxiation.

In contrast, other symptoms, such as those listed in option D, might indicate a more advanced state of respiratory distress, while options A and C do not strongly signify asphyxiation as they encompass symptoms that can arise from a variety of conditions, rather than being specifically tied to low oxygen levels in the body.
