Lactic acid fermentation occurs in your muscles after a workout because your cells are struggling to get
A
Glucose
B
Sunlight
C
Oxygen
D
Water
Explanation: 

Detailed explanation-1: -Muscle cells opt for lactic acid fermentation due to less availability of oxygen. In this process they produce lactic acid and less energy per glucose molecule.

Detailed explanation-2: -Humans undergo lactic acid fermentation when the body needs a lot of energy in a hurry. When you are sprinting full speed, your cells will only have enough ATP stored in them to last a few seconds. Once the stored ATP is used, your muscles will start producing ATP through lactic acid fermentation.

Detailed explanation-3: -Lactic acid accumulates in your muscle cells as fermentation proceeds during times of strenuous exercise. During these times, your respiratory and cardiovascular systems cannot transport oxygen to your muscle cells, especially those in your legs, fast enough to maintain aerobic respiration.

Detailed explanation-4: -Fermentation does not require oxygen and is therefore anaerobic. Fermentation will replenish NAD+ from the NADH + H+ produced in glycolysis.
