Options

A. Zygomatic
B. Parotids
C. The sub-maxillary / sub-mandibular (lower jaw)
D. The sub-linguals (below the tongue)

Answer

To answer the question "Which of the following salivary gland is absent in human beings?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks which salivary gland is not present in humans. We need to identify the salivary glands that are typically found in humans and then determine which one is absent.

2. **Identify the Salivary Glands in Humans**: Humans have three pairs of major salivary glands:
- **Parotid Gland**: The largest salivary gland located outside the buccal cavity and below the ear.
- **Submandibular (or Submaxillary) Gland**: Located in the lower jaw.
- **Sublingual Gland**: Located below the tongue.

3. **Examine the Options**: The question provides options, and we need to evaluate each one to see if it corresponds to a known salivary gland in humans.
- **Option 1: Zygomatic**: This is not a salivary gland; it refers to the cheekbone (zygomatic bone) in humans.
- **Option 2: Parotid**: This is a salivary gland present in humans.
- **Option 3: Submandibular**: This is also a salivary gland present in humans.
- **Option 4: Sublingual**: This is another salivary gland present in humans.

4. **Determine the Correct Answer**: Since the zygomatic is not a salivary gland and is instead a bone, it is the only option that is absent as a salivary gland in humans.

5. **Conclusion**: The correct answer is that the **Zygomatic gland** is absent in humans as it is not a salivary gland.

### Final Answer:
The salivary gland that is absent in human beings is the **Zygomatic gland**.
