Oliguria
Elevated blood pressure

The Correct Answer is B
Oliguria is a condition where the urine output is less than normal, usually less than 500 mL per day in adults. Oliguria can be a sign of dehydration, which occurs when the body loses more water than it takes in. Dehydration can cause various symptoms such as thirst, dry mouth, headache, dizziness, fatigue, and confusion.
Dehydration can also affect kidney function and lead to electrolyte imbalances and acid-base disorders.

Lymphedema is a chronic condition that occurs when the lymphatic system is impaired and cannot drain excess fluid from the tissues, resulting in swelling and discomfort in one or more limbs or body parts. It can be caused by an obstruction in the lymphatic system due to surgery, radiation therapy, infection, injury, or congenital malformation.
Correct Answer is C
Explanation
Vitamin B12 is a water-soluble vitamin that is involved in the production of red blood cells, DNA synthesis, and nerve function. Vitamin B12 deficiency can cause anemia, neurological problems, and cognitive impairment. Vitamin B12 deficiency can be attributed to alcoholism because alcohol interferes with the absorption and metabolism of vitamin B12 in the stomach and liver. Alcohol also damages the lining of the intestines, where vitamin B12 is absorbed from food sources.
