What is a secondary function of the lymphatic system?

I believe the correcrtanswer is B. Fighting infection.
<h2>Explanation: </h2>The lymphatic system has special tissues called the lymph nodes that produce and contain white blood cells to help the body fight infections. Its primary function is to maintain fluid balance and the other function is absorbing fatty acids and transporting fats and chyle to the rest of the body.
<h2>Further Explanation: </h2>During normal functioning of the body, fluids move from blood into tissues as they transport oxygen and nutrients to the tissues and carbon dioxide and other wastes away from the tissues. The fluid that is excess in the tissues needs to be removed from the tissues involved and that is where the lymphatic system functions primarily. The secondary function is fighting infections by producing white blood cells and pooling them in places affected by infections. The white blood cells produced by the lymph nodes of the lymphatic system are classified depending on the arrangement of their nucleuses, cellular granules, color of granules and their shape and size.
The cells include lymphocytes that fight viral infections such as influenza and HIV, neutrophils that fight bacterial infections that cause conditions such as typhoid and step throats, eosinophils that fight parasites that cause diseases such as malaria and trypanosomiasis, basophils that help the body respond to allergies such as in hay fever or allergies to fur from pets, monocytes that also fight bacteria and plasma cells that are specialized types of lymphocytes called B-lymphocytes that fight cancers and viruses. The cells are suspended in lymph and they are transported to any site that is needed to fight infections or disease causing antigens. You can observe the action of lymph nodes when a person gets a cut in his leg. Due to the cut, the lymph nodes in the groin region will start producing many white blood cells to fight the infection on the foot making the corners of the groin to swell in relation to the foot that is affected. Lymph nodes can be found in areas such as the neck, under the chin on both the left and right side, in the armpit region and the groin.

Answer:
Alcohol fermentation
Explanation:
When oxygen availability is low, the cell can't perform aerobic respiration to breakdown glucose. Instead, anaerobic respiration must be performed. This occurs in cells which consume large amounts of energy, such as muscle cells. Anaerobic respiration produces much less energy than aerobic respiration
One type of anaerobic respiration formed by yeast is called alcohol fermentation (also called ethanol fermentation). This begins with glycolysis, where one molecule of glucose is broke down into 2 molecules of pyruvate. The energy from this reaction generates 2 molecules of ATP, and converts NAD+ to NADH.
Then, the two molecules of pyruvate are further broke down into 2 acetaldehydes (releasing two molecules of carbon dioxide as a by-product). These two molecules of acetaldehyde are then converted into tw molecules of ethanol, using the H ions from NADH, converting it back to NAD+. See the attached picture
This process is taken advantage of to brew beer and wine.
