To determine which vitamin is antihaemorrhagic, we can follow these steps:

### Step 1: Understand the term "antihaemorrhagic"
- Antihaemorrhagic refers to substances that prevent or reduce bleeding. In the context of vitamins, we are looking for a vitamin that plays a crucial role in blood clotting and wound healing.

### Step 2: Review the options provided

### Step 3: Recall the functions of each vitamin
- **Vitamin B12**: Primarily involved in red blood cell formation and neurological function.
- **Vitamin B5**: Important for the synthesis of coenzyme A and fatty acid metabolism.
- **Vitamin C**: Known for its role in collagen synthesis and as an antioxidant; it also aids in the absorption of iron but is not directly involved in blood clotting.
- **Vitamin K**: Essential for the synthesis of proteins required for blood coagulation (clotting).

### Step 4: Identify the antihaemorrhagic vitamin
