A. Nereis
B. Hirudinaria
C. Tapeworm
D. Earthworm

Answer

To determine which animal is sanguivorous, we can follow these steps:

### Step 1: Understand the term "sanguivorous"
- Sanguivorous refers to animals that feed on blood. This means we are looking for organisms that have a diet consisting mainly of blood.

### Step 2: Identify examples of sanguivorous animals
- Common examples of sanguivorous animals include certain species of bats and leeches. Bats, particularly vampire bats, are known for their blood-feeding behavior.

### Step 3: Differentiate between sanguivorous and non-sanguivorous animals
- Not all animals in the same category feed on blood. For example, while some leeches (like Hirudo medicinalis) are sanguivorous, earthworms, which also belong to the Annelida phylum, do not feed on blood.

### Step 4: Analyze the options provided
- If the options include animals like bats or leeches, we can identify which of these are sanguivorous. For instance, Hirudo (the freshwater leech) is a sanguivorous organism.

### Step 5: Conclude with the correct answer
- Based on the analysis, the correct answer to the question "The animal which is sanguivorous is" would be the leech (Hirudo) or a vampire bat, depending on the options provided.

### Final Answer:
The animal which is sanguivorous is the leech (Hirudo) or a vampire bat.
