## **Core Concept**
Urban malaria is a form of malaria that occurs in urban areas, typically caused by a specific species of Plasmodium. The disease is transmitted by the bite of an infected female Anopheles mosquito. Understanding the causative agent is crucial for diagnosis and treatment.

## **Why the Correct Answer is Right**
The correct answer, **Plasmodium vivax** and **Plasmodium ovale** are not typically associated with urban malaria; however, **Plasmodium falciparum** is a major cause, but in the context of urban malaria, especially in regions like India, **Plasmodium vivax** is notably prevalent. Urban malaria is often linked to **Plasmodium vivax** due to its ability to be transmitted in urban settings by *Anopheles stephensi*, a mosquito that can breed in small, artificial water collections.

## **Why Each Wrong Option is Incorrect**
- **Option A:** If this option does not correspond to *P. vivax*, then it is incorrect based on the specifics of urban malaria causes.
- **Option B:** Similarly, if this does not align with *P. vivax* or is another incorrect species, it's wrong.
- **Option D:** This option is incorrect if it suggests another Plasmodium species not primarily associated with urban malaria.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that urban malaria, particularly in areas like India, is significantly caused by **Plasmodium vivax**, transmitted by *Anopheles stephensi*. This is a critical distinction for clinicians, especially in regions where both *P. falciparum* and *P. vivax* are prevalent.

## **Correct Answer:** C. Plasmodium vivax.
