**Why the Correct Answer is Right**
The patient's symptoms are consistent with molluscum contagiosum, a viral skin infection caused by the molluscum contagiosum virus (MCV). MCV infects the keratinocytes, leading to the formation of characteristic umbilicated papules. The virus replicates within the cytoplasm of the infected cells, causing the formation of large, eosinophilic inclusion bodies. The skin lesions are often accompanied by mild inflammation and can be itchy or tender to the touch.
**Why Each Wrong Option is Incorrect**

**Option C:** This option is incorrect because it does not match the description of the skin lesions or the presentation of the disease.
**Clinical Pearl / High-Yield Fact**
