**Core Concept**
Lobar pneumonia is characterized by an inflammatory process in one or more lobes of the lung, typically caused by Streptococcus pneumoniae. The disease progression involves several stages, including consolidation, resolution, and healing. The type of exudate present in each stage is crucial in determining the stage of the disease.

**Why the Correct Answer is Right**
Fibrinosuppurative exudate with disintegration of red cells is a characteristic feature of the stage of resolution in lobar pneumonia. During this stage, the inflammatory process starts to resolve, and the exudate begins to break down. The fibrin network in the exudate starts to disintegrate, leading to the presence of fibrinosuppurative exudate with disintegration of red cells. The breakdown of red cells is due to the enzymatic action of leukocytes, which release enzymes that break down the cellular components of the exudate.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the stage of consolidation is characterized by the presence of a homogeneous, grayish-red exudate, not fibrinosuppurative exudate with disintegration of red cells.

**Option B:** This option is incorrect because the stage of resolution is not characterized by the presence of a large number of neutrophils; instead, it is characterized by the presence of lymphocytes and plasma cells.

**Option C:** This option is incorrect because the stage of healing is characterized by the presence of fibrosis and scarring, not fibrinosuppurative exudate with disintegration of red cells.

**Clinical Pearl / High-Yield Fact**
Remember that the type of exudate present in lobar pneumonia can be used to determine the stage of the disease. A fibrinosuppurative exudate with disintegration of red cells is a hallmark of the resolution stage, while a homogeneous, grayish-red exudate is characteristic of the consolidation stage.

**Correct Answer:** C.
