**Core Concept**
Blood storage is a critical process that requires precise temperature control to maintain the viability and functionality of red blood cells (RBCs). The temperature at which blood is stored affects the metabolic rate of RBCs, enzyme activity, and hemolysis.

**Why the Correct Answer is Right**
Blood is typically stored at a temperature range of 2°C to 6°C (35.6°F to 42.8°F) to slow down the metabolic processes in RBCs. This temperature range is ideal for preserving the integrity of RBCs, preventing hemolysis, and maintaining their ability to carry oxygen. The storage at this temperature range also helps to slow down the formation of microaggregates and the activation of complement system, which can lead to hemolysis.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because temperatures above 10°C (50°F) can lead to rapid hemolysis and degradation of RBCs, making them unsuitable for transfusion.
* **Option B:** This option is incorrect because temperatures below 0°C (32°F) can cause the formation of ice crystals within the RBCs, leading to cell lysis and hemolysis.
* **Option C:** This option is incorrect because room temperature (approximately 20°C or 68°F) is too high for blood storage, leading to rapid degradation of RBCs and hemolysis.

**Clinical Pearl / High-Yield Fact**
It is essential to note that blood storage duration is limited, and it is recommended to use blood within 21 to 35 days of storage, depending on the storage conditions and the type of blood product.

**Correct Answer:** C.
