**Core Concept**
Whole blood storage is a critical aspect of transfusion medicine, requiring careful consideration of the blood components and storage conditions to maintain viability and safety. The primary goal is to preserve the integrity of red blood cells, platelets, and plasma components.

**Why the Correct Answer is Right**
Whole blood is typically stored at 2-6°C in a manner that prevents agitation and exposure to light, which can cause hemolysis. The storage conditions aim to slow down the metabolic processes in red blood cells, maintaining their viability for transfusion. The ideal storage duration for whole blood is 21-35 days, depending on the storage conditions and the specific blood bank protocols.

**Why Each Wrong Option is Incorrect**
**Option A:** Not relevant to whole blood storage.
**Option B:** Not a standard storage condition for whole blood.
**Option C:** Incorrect storage condition, as whole blood is not typically stored at room temperature.

**Clinical Pearl / High-Yield Fact**
Whole blood storage requires careful consideration of the storage conditions to maintain the viability of red blood cells and other blood components. It is essential to follow established protocols and guidelines for blood storage to ensure the safety and efficacy of transfusions.

**Correct Answer: C. 2-6°C**
