Answer: (C)

Verified step by step guidance

1. Step 1: Understand the definition of a fracture. A fracture refers to a break in the continuity of a bone, which can vary in severity and type.
2. Step 2: Review the characteristics of an open (compound) fracture. This type of fracture involves a complete break in the bone where the broken ends pierce through the skin, exposing the bone to the external environment.
3. Step 3: Examine the features of a comminuted fracture. In this type, the bone is shattered into multiple fragments, but it does not necessarily involve piercing through the skin.
4. Step 4: Learn about a greenstick fracture. This occurs when the bone bends and partially breaks, typically seen in children whose bones are more flexible. It is not a complete break.
5. Step 5: Understand the closed (simple) fracture. This type of fracture involves a complete break in the bone, but the skin remains intact, meaning the bone does not pierce through the skin. This matches the description in the problem.
