**Core Concept**
The procedure of pleural tapping, also known as thoracocentesis, involves the insertion of a needle into the pleural space to drain fluid. This is typically performed in the midaxillary line, where the risk of injuring major organs or muscles is minimized. Understanding the anatomy of the thoracic wall is crucial for safely performing this procedure.

**Why the Correct Answer is Right**
During pleural tapping in the midaxillary line, the needle passes through several layers of tissue, including skin, subcutaneous tissue, and muscle. The muscles encountered in this region include the latissimus dorsi and the serratus anterior. However, the correct answer choice is not provided, so let's proceed with the general knowledge that the pectoralis major muscle is not in the midaxillary line.

**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific answer choices, we cannot directly address why each option is incorrect. Generally, muscles like the latissimus dorsi are pierced during this procedure.
**Option B:** Similarly, without the specific options, we can't discuss the incorrectness directly, but muscles such as the serratus anterior might be involved.
**Option C:** and **Option D:** would follow similar reasoning, focusing on the anatomical location and the muscles typically encountered during a midaxillary pleural tap.

**Clinical Pearl / High-Yield Fact**
A key point to remember is the anatomy of the thoracic wall and the location of muscles and other structures relative to the midaxillary line. This knowledge helps in minimizing complications during procedures like pleural tapping.

**Correct Answer:** Correct Answer: D. Pectoralis major.
