**Core Concept:**
Tenia solium, also known as pork tapeworm, is a parasitic infection caused by the larval stage of the pork tapeworm (Cysticercus cellulosae). Humans become infected when they consume contaminated food or water, typically from eating undercooked pork containing the cysticerci larvae. The infection can lead to various clinical manifestations, depending on the location and number of cysts in the body.

**Why the Correct Answer is Right:**
The correct answer is **Option D: Mebendazole**. Mebendazole is a benzimidazole anthelmintic drug primarily used for the treatment of helminth infections, including strongyloidiasis, filariasis, and ascariasis. However, Mebendazole is not effective against cestode infections like those caused by Taenia solium, since the drug's mechanism of action primarily targets nematodes and not cestodes.

**Why Each Wrong Option is Incorrect:**
Option A: **Pyrantel pamoate** is an anthelmintic drug used for the treatment of filariasis, ascariasis, and trichuriasis, but it is not effective against cestode infections.
Option B: **Thiabendazole** is a benzimidazole anthelmintic drug used for the treatment of several helminth infections, but it is also not effective against cestode infections.
Option C: **Praziquantel** is a polyether ionophore anthelmintic drug used for treating infections caused by cestodes (tapeworms) and trematodes (fluke infections). It is a suitable treatment option for cestode infections, making it incorrect in this context.

**Clinical Pearl:**
In Tenia solium infection, the standard treatment involves administering praziquantel, which is effective against cestode infections. Since Mebendazole is ineffective against cestodes, it is crucial to recognize the correct drug for the appropriate treatment of Taenia solium infections, as this knowledge is essential for clinical practice and patient management.
