**Core Concept**
The intermediate host for Taenia saginata, also known as the beef tapeworm, is an animal that harbors the larval stages of the parasite. This concept is crucial in understanding the life cycle of Taenia saginata and its transmission to humans.

**Why the Correct Answer is Right**
The correct answer is a cattle, which serves as the intermediate host for Taenia saginata. When an infected human consumes undercooked beef containing cysticerci, the larvae can penetrate the intestinal wall and mature into adult tapeworms in the human host. However, the initial development of the parasite occurs in the intermediate host, which is the cattle. The cysticerci in the cattle are ingested by humans, leading to the infection.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it is not a known intermediate host for Taenia saginata. The intermediate host for Taenia saginata is specifically the cattle.
**Option B:** This option is incorrect because it is a definitive host for Taenia saginata, not the intermediate host. Humans are the definitive hosts where the adult tapeworms mature and reproduce.

**Clinical Pearl / High-Yield Fact**
To prevent the transmission of Taenia saginata, it is essential to cook beef thoroughly, especially when consuming raw or undercooked meat. This can help prevent the ingestion of cysticerci and subsequent infection.

**Correct Answer:** C.
