## Core Concept
Wolff's law, also known as the law of bone remodeling, states that bone adapts to the loads under which it is placed. This principle is fundamental in understanding how bones change shape and density in response to mechanical stress.

## Why the Correct Answer is Right
The correct completion of Wolff's law is: "Bone will adapt to the loads under which it is placed." This means that if a bone is subjected to increased stress or load, it will remodel itself to become stronger and better able to withstand that load. This process involves the coordinated action of osteoclasts (which resorb bone) and osteoblasts (which form new bone). The law is crucial for understanding bone health, the effects of exercise on bone density, and the pathophysiology of conditions like osteoporosis.

## Why Each Wrong Option is Incorrect
- **Option A:** This option is incomplete and does not accurately reflect Wolff's law. Without the specific text, we can infer that it likely misses the core concept of bone adapting to loads.
- **Option B:** Similarly, this option is incorrect because it does not correctly state Wolff's law. It might be a partial statement or an unrelated concept.
- **Option C:** This is the correct statement of Wolff's law, which we've identified as "Bone will adapt to the loads under which it is placed."
- **Option D:** This option is also incorrect as it does not accurately represent Wolff's law. Like options A and B, without the specific text, we infer it's incorrect based on the known correct statement.

## Clinical Pearl / High-Yield Fact
A key clinical application of Wolff's law is in the management and prevention of osteoporosis. Regular weight-bearing exercise can stimulate bone formation and increase bone density, reducing the risk of fractures. This principle underlies many physical therapy and rehabilitation strategies aimed at improving bone health.

## Correct Answer: C. Bone will adapt to the loads under which it is placed.
