**Core Concept**
Visceral larva migrans (VLM) is a condition characterized by the migration of larvae of certain nematodes through the tissues of a non-suitable host, typically a human. This condition is a result of the ingestion of eggs of the parasite, which then hatch and cause tissue damage during their migration.

**Why the Correct Answer is Right**
The correct answer is caused by the larvae of **Toxocara cati**, a parasitic nematode commonly found in cats. The eggs of Toxocara cati are ingested by humans, either through contaminated food or soil, and the larvae then hatch and migrate through the body, causing inflammation and tissue damage. This condition is often seen in children who have poor hygiene and are exposed to contaminated soil or cat feces.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because VLM is not caused by Trichinella spiralis, which causes trichinosis, a different parasitic infection.
**Option B:** This option is incorrect because Anisakis larvae cause anisakiasis, a parasitic infection of the gastrointestinal tract, but not visceral larva migrans.
**Option C:** This option is incorrect because Strongyloides stercoralis causes strongyloidiasis, which is a different type of parasitic infection that involves the migration of larvae through the body, but it is not the same as visceral larva migrans.

**Clinical Pearl / High-Yield Fact**
Toxocara cati eggs can be found in contaminated soil, cat feces, and other environments, making it essential for individuals, especially children, to practice good hygiene and avoid touching their faces or mouths after exposure to potentially contaminated environments.

**Correct Answer:** C.
