Well because your heart beat is increasing very rapidly your hearts output will speed up or increase. This happens because the heart is beating faster forcing it to pump blood threw you at a more efficient or higher rate. This increased flow of blood is very important for your lungs because with an increased heart rate comes increased breaths meaning your lungs are relying on that blood flow to be able to release oxygen into your fast flowing blood stream. Which that oxygenated blood will then fuel the rest of your body. Sorry if this is kinda a mess but pretty much the main idea is your body needs an more blood flow per minute because it allows the rest of your body to function as fast and efficiently as your heart.
My answer would be B or A. You could do both of those while watching TV.
Hemostatic drug
Antibiotics are used to treat an infection, so it wouldn’t be that one. Thrombolytic drugs are used to prevent blood clots, and they thin blood. So not that one. Coagulant drugs are used to thicken things, but this is a anticoagulant. Meaning it will thin it. I think the only logical answer would be hemostatic drug.
