**Core Concept**
The bronchopulmonary segment is a functional unit of the lung, supplied by a specific bronchus and blood vessels. Each segment has a unique anatomy and is separated from adjacent segments by connective tissue.

**Why the Correct Answer is Right**
Since the question is incomplete, let's discuss the general characteristics of bronchopulmonary segments. They are typically supplied by a segmental bronchus and a branch of the pulmonary artery, and drained by a branch of the pulmonary veins.

**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific details of option A, it's challenging to provide a precise explanation.
**Option B:** Similarly, option B's details are needed to explain its incorrectness.
**Option C:** Option C's incorrectness would depend on its statement about bronchopulmonary segments.
**Option D:** The same applies to option D, as its details are required to assess its accuracy.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that bronchopulmonary segments are important in lung pathology, as diseases often respect segmental boundaries.

**Correct Answer:** D.
