**Core Concept**
Alcoholic hyaline, also known as Mallory-Denk bodies, is a characteristic histopathological feature of alcoholic liver disease. These structures are composed of intermediate filament proteins that accumulate in the cytoplasm of hepatocytes due to oxidative stress and damage.

**Why the Correct Answer is Right**
The correct answer is composed of intermediate filament proteins, specifically cytokeratins 8 and 18. The formation of Mallory-Denk bodies is associated with chronic alcohol consumption, leading to the disruption of normal cellular processes and the accumulation of abnormal proteins. The presence of these bodies is a hallmark of alcoholic liver disease, particularly in the context of steatosis, steatohepatitis, and cirrhosis.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because Mallory-Denk bodies are not composed of actin filaments, which are involved in muscle contraction and cytoskeletal structure.
* **Option B:** This option is incorrect because Mallory-Denk bodies are not composed of collagen, which is a major component of the extracellular matrix in connective tissue.
* **Option C:** This option is incorrect because Mallory-Denk bodies are not composed of elastin, which is a protein that provides elasticity to connective tissue.

**Clinical Pearl / High-Yield Fact**
The presence of Mallory-Denk bodies is a strong indicator of chronic alcohol consumption and can be used as a diagnostic clue in patients with liver disease. However, it's essential to note that these bodies can also be seen in other conditions, such as non-alcoholic steatohepatitis and autoimmune hepatitis.

**Correct Answer: C. Intermediate filament proteins.**
