**Core Concept**
The concept being tested is related to the mode of transmission of infectious diseases, specifically the idea of a carrier who receives the source of infection from another carrier. This is a key principle in public health and epidemiology, as it helps in understanding the spread of diseases.

**Why the Correct Answer is Right**
A carrier who receives the source of infection from another carrier is called a "secondary carrier". This occurs when an individual comes into contact with an infected person, either directly or indirectly, and becomes a carrier themselves. For example, in the case of typhoid fever, a secondary carrier can become infected through close contact with a primary carrier who has not yet shown symptoms.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is not relevant to the concept of a carrier receiving the source of infection from another carrier.
* **Option B:** This option is incorrect as it refers to a different concept in epidemiology.
* **Option D:** This option is not a recognized term in the context of infectious disease transmission.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that secondary carriers can play a significant role in the spread of infectious diseases, especially in settings where hygiene and infection control practices are inadequate.

**Correct Answer:** C.
