**Core Concept**
The process of bone biopsy involves **decalcification** and **fixation** to analyze the bone tissue properly. Decalcification is the removal of calcium salts from bone tissue, while fixation preserves the tissue structure.

**Why the Correct Answer is Right**
The correct answer involves a method that allows for simultaneous decalcification and fixation. This process is crucial for maintaining the integrity of the bone tissue for further analysis.

**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because it does not involve simultaneous decalcification and fixation.
**Option B:** Incorrect as it is not typically used for this purpose.
**Option C:** Incorrect because it is not the standard method for simultaneous decalcification and fixation.

**Why Each Wrong Option is Incorrect (Continued)**
**Option D:** Is the correct answer choice, so it will be discussed in the correct answer line.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that **bone biopsy** requires careful handling to preserve the tissue. Simultaneous decalcification and fixation is a critical step in this process.

**Correct Answer:** D. Ethylenediaminetetraacetic acid (EDTA)
