• D. Sternum

Answer: (D)

Verified step by step guidance

1. Step 1: Understand the question by identifying the anatomical terms and landmarks mentioned. The question asks for a bony landmark that can be palpated on the anterior surface of the body, close to the midline.
2. Step 2: Review the anatomical location of each option provided: Acromion, Iliac crest, Scapula, and Sternum. The Acromion is part of the scapula and located on the shoulder, not near the midline. The Iliac crest is part of the pelvis and located laterally, not near the midline. The Scapula is a posterior structure of the shoulder blade, not anterior.
3. Step 3: Focus on the Sternum. The Sternum is a flat bone located on the anterior surface of the thorax, close to the midline. It is easily palpated and serves as an attachment point for ribs and the clavicle.
4. Step 4: Confirm the anatomical position of the Sternum. It is centrally located in the chest and forms part of the rib cage, protecting vital organs such as the heart and lungs.
5. Step 5: Conclude that the Sternum is the correct answer based on its anterior location, proximity to the midline, and palpability.
