Well, we know for sure the myoglobin oxygen is going to be consumed and the capillary density will increase
So only choice 4 is the likely correct

The sequence of events is like this

decreased oxygen concentration will induce vascular endothelial growth factor which will increase the capillary density but I think one hour is not enough to for the capillary to grow, therefore the most likely correct answer is option 5
