**Core Concept**
The **direct ophthalmoscope** is used for a detailed examination of the **fundus**, allowing visualization of the **retina**, **macula**, **optic disc**, and **retinal vessels**. This method provides a highly magnified view but has a narrow field of view.

**Why the Correct Answer is Right**
Since the question is incomplete, a general approach to direct ophthalmoscopy will be discussed. Direct ophthalmoscopy allows for the examination of the fundus in detail, including the **optic disc** for signs of **papilledema** or **optic atrophy**, the **macula** for **macular degeneration**, and the **retinal vessels** for signs of **hypertension** or **diabetic retinopathy**.

**Why Each Wrong Option is Incorrect**
**Option A:** Without the specific details of each option, it's challenging to address each directly. Normally, incorrect options might include features not observable with a direct ophthalmoscope or characteristics of indirect ophthalmoscopy.
**Option B:** Similar to Option A, without specifics, we can't directly refute each choice.
**Option C:** This option would be incorrect if it described a feature not associated with direct ophthalmoscopy, such as a wide field of view, which is more characteristic of indirect ophthalmoscopy.
**Option D:** This might be incorrect if it mentioned a feature that is actually a benefit or characteristic of direct ophthalmoscopy.

**Clinical Pearl / High-Yield Fact**
A key point to remember is that direct ophthalmoscopy provides a magnified but narrow view of the fundus, making it ideal for examining the details of the retina and optic disc.

**Correct Answer:** Correct Answer: D. Inability to see the peripheral retina.
