Explanation

**Step-by-Step Solution:**

1. **Understanding Plasma**: Plasma is the liquid component of blood, making up about 55% of its total volume. It consists mostly of water (around 92%) and contains various proteins, nutrients, hormones, and waste products.

2. **Identifying Fibrinogen**: Fibrinogen is a specific protein found in plasma that plays a crucial role in the blood clotting process. When blood is injured, fibrinogen is converted into fibrin, which helps form a clot.
