**Core Concept**
Kidney disease, also known as nephropathy, refers to the damage or impairment of the kidneys, which can lead to various systemic effects due to the accumulation of waste products and electrolyte imbalances. The kidneys play a crucial role in maintaining fluid balance, regulating blood pressure, and preventing electrolyte imbalances.

**Why the Correct Answer is Right**
The common manifestations of kidney disease are primarily related to the accumulation of waste products and electrolyte imbalances. These manifestations include edema, hypertension, electrolyte disturbances (such as hyperkalemia and hypocalcemia), uremia, and anemia. The kidneys also produce erythropoietin, a hormone that stimulates red blood cell production, so anemia is a common finding in kidney disease. Additionally, kidney disease can lead to metabolic acidosis due to the kidneys' inability to excrete hydrogen ions.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incomplete and does not provide any information about kidney disease manifestations.
**Option B:** This option is incorrect because while kidney disease can lead to anemia, it is not the only manifestation.
**Option C:** This option is incorrect because while hypertension can be a manifestation of kidney disease, it is not the only one.

**Clinical Pearl / High-Yield Fact**
A key clinical finding in kidney disease is the presence of uremic breath, which is characterized by a metallic or ammonia-like odor due to the accumulation of waste products. This is a high-yield fact for exam purposes.

**Correct Answer:** A. Edema, hypertension, electrolyte disturbances, uremia, anemia.
