Ok when we inhale we are letting oxygen inside of us, that oxygen that we inhale helps our blood move around our bodies. When we breath out taking out all the old air thats called carbon dioxide and it is very dangerous because it can make us stop breathing if we dont find new oxygen fast. Please if you need more info just private message me.
Many things can cause shortness of breath, but the most common are asthma, pneumonia, bronchitis, lung cancer, anxiety, an allergic reaction, a lung injury, obesity, heart dysfunction, COPD and many many more things.
As for treating this, see your physician. Hope I helped you!
Im pretty sure it's "D"... Hope this helps! :)
