B. Hip bone
C. Scapula
D. Sacrum

Answer

**Step-by-Step Solution:**

1. **Understand the Description**: The question describes a bone that is large, triangular, and flat, located in the dorsal part of the thorax between the second and seventh ribs.

2. **Identify the Location**: The dorsal part of the thorax refers to the back area of the chest. The ribs mentioned (second to seventh) help narrow down the specific area of the body where this bone is located.

3. **Recall Relevant Bones**: In human anatomy, the bones located in the dorsal thorax include the scapula (shoulder blade) and the vertebrae. The scapula is known to be a flat, triangular bone.

4. **Confirm the Characteristics**: The scapula fits the description of being large, triangular, and flat. It is also positioned between the ribs mentioned (second to seventh).

5. **Consider Other Options**: The question provides options, and it is important to eliminate those that do not fit. The femur is the thigh bone, the hip bone is part of the pelvic girdle, and the sacrum is part of the vertebral column. None of these are located in the dorsal thorax.

6. **Conclude the Answer**: Based on the characteristics and location, the bone described in the question is identified as the scapula.

**Final Answer**: The bone is the **scapula**.
