Answer:
Glycolysis is a series of reactions that take place in the cell cytoplasm. It involves the oxidation of glucose into pyruvate (a 3 carbon compound), that produces (overall)ATP and reduced NAD: an enzyme that carries hydrogen. The number of carbons in each of these compounds is indicated in the green circle.
The carriers FAD and NAD bring the hydrogen and it separates to H+ and electrons (e-). The electrons pass from carrier to carrier and loose energy. This is used to synthesize ATP.
However, there are a lot of hydrogen ions, that unless they are removed, they'll cause a large increase in pH. Therefore, oxygen reacts with the ions to remove it and produce water. This is what the oxygen you inhale is used for (in terms of respiration).

Option A) is correct.
Explanation:
Electromagnetic waves refer to waves that are created due to vibrations between a magnetic field and an electric field.
Electromagnetic waves do not require a medium to travel through space without a medium. Electromagnetic waves can travel through air, vacuum of space and solid materials.
So,
