An acromian process is characteristically found in the

Options

A. Skull of frog
B. sperm of mammals
C. pelvic girdle of mammals
D. pectoral girdle of mammals

Answer

**Step-by-Step Solution:**

1. **Understanding the Acromion Process**: The acromion process is a bony structure that is part of the skeletal system. It is important to identify where this structure is located within the body.

2. **Identifying Possible Locations**: The question provides four options where the acromion process could be found:
- Skull of the frog
- Sperm of the mammal
- Pelvic girdle of the mammal
- Pectoral girdle of the mammal

3. **Analyzing Each Option**:
- **Skull of the Frog**: The acromion process is not found in the skull of a frog as it is not a structure associated with amphibians.
- **Sperm of the Mammal**: The acromion process is not related to sperm, as it pertains to skeletal structures.
- **Pelvic Girdle of the Mammal**: The pelvic girdle does not contain the acromion process; it is associated with the lower body.
- **Pectoral Girdle of the Mammal**: The acromion process is indeed found in the pectoral girdle, specifically as part of the scapula.

4. **Conclusion**: Based on the analysis, the acromion process is characteristically found in the pectoral girdle of the mammal.

5. **Explanation of the Structure**: The acromion is formed from the scapula, which is one of the two bones that make up the pectoral girdle (the other being the clavicle). The scapula has a spine that extends and leads to the formation of the acromion, which is a flattened and expanded structure.

**Final Answer**: The acromion process is characteristically found in the pectoral girdle of the mammal.
