**Core Concept**
The question is asking about the mode of transmission of *Dermatophytosis*, a fungal infection caused by dermatophytes. The correct answer is related to the specific dermatophyte species, *D.latum*, also known as *Trichophyton rubrum*.

**Why the Correct Answer is Right**
* *D.latum*, or *Trichophyton rubrum*, is a dermatophyte that primarily infects the skin, hair, and nails. It is transmitted through direct contact with an infected person or contaminated objects. This dermatophyte thrives in warm, moist environments, making it a common cause of fungal infections in humans.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is not relevant to the transmission of *D.latum*.
* **Option B:** This option is incorrect as it is not a known mode of transmission for *D.latum*.
* **Option C:** This option may be a mode of transmission for other pathogens, but not specifically for *D.latum*.

**Clinical Pearl / High-Yield Fact**
* *D.latum* can cause a range of symptoms, from mild skin lesions to severe infections, and can be diagnosed through clinical examination and laboratory tests such as potassium hydroxide (KOH) preparation.

**Correct Answer:** C. Contaminated objects.
