**Core Concept**
The question is testing the diagnosis of a condition characterized by recurrent ulcers on the glans penis, which heals with hyperpigmentation. This condition is a type of sexually transmitted infection (STI) that affects the genital area.

**Why the Correct Answer is Right**
The probable diagnosis is Donovanosis, also known as granuloma inguinale. It is caused by the bacterium Klebsiella granulomatis, formerly known as Calymmatobacterium granulomatis. The bacteria infect the skin and mucous membranes of the genital area, leading to the formation of ulcers. The ulcers are typically painless and bleed easily, and they heal with hyperpigmentation, leaving behind a characteristic "beefy red" appearance. Donovanosis is a notifiable disease, and its diagnosis is based on clinical presentation, along with laboratory tests such as Gram stain, Giemsa stain, and PCR.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because the condition described does not match the typical presentation of Herpes Simplex Virus (HSV) infection, which is characterized by painful vesicles or ulcers.

**Option B:** This option is incorrect because the condition described does not match the typical presentation of Syphilis, which is characterized by a painless chancre at the site of initial infection, followed by a rash and other systemic symptoms.

**Option C:** This option is incorrect because the condition described does not match the typical presentation of Chancroid, which is caused by Haemophilus ducreyi and characterized by painful ulcers and tender lymphadenopathy.

**Clinical Pearl / High-Yield Fact**
Donovanosis is a sexually transmitted infection that can be transmitted through direct contact with an infected person's genital area, and it is more common in tropical and subtropical regions. It can be treated with antibiotics, and prompt treatment is essential to prevent long-term complications and transmission to others.

**Correct Answer:** C.
