**Core Concept**
Mesothelioma of the pleura is a malignant tumor arising from the pleural mesothelium, a layer of cells lining the pleural cavity. This condition is primarily associated with asbestos exposure, leading to chronic inflammation and subsequent malignant transformation.

**Why the Correct Answer is Right**
The biopsy of mesothelioma of the pleura typically reveals a biphasic pattern, consisting of both epithelioid and sarcomatoid components. The epithelioid component is characterized by large, polygonal cells with abundant cytoplasm and hyperchromatic nuclei, often forming gland-like or tubular structures. The sarcomatoid component is composed of spindle-shaped cells with a desmin-positive and cytokeratin-negative immunoprofile, resembling fibrosarcoma or malignant fibrous histiocytoma. The presence of these two components is a hallmark of pleural mesothelioma, distinguishing it from other malignant pleural tumors.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect as it does not accurately describe the histological features of mesothelioma. While it may be a feature of other pleural tumors, it is not specific or diagnostic for mesothelioma.
**Option B:** This option is incorrect as it describes a histological pattern more characteristic of adenocarcinoma or other epithelial tumors, rather than mesothelioma.
**Option C:** This option is incorrect as it is a feature of benign conditions such as pleural fibrosis or asbestos-related pleural plaques, rather than malignant mesothelioma.

**Clinical Pearl / High-Yield Fact**
In the context of pleural disease, it is essential to distinguish between benign and malignant conditions, as the management and prognosis differ significantly. A high index of suspicion for mesothelioma should be maintained in patients with a history of asbestos exposure, particularly those presenting with pleural effusion or pleural thickening.

**Correct Answer:** C.
