**Core Concept**
The question tests understanding of **paralytic squint**, specifically **convergent squint**, and its effects on vision, including **diplopia**. Convergent squint occurs when an eye turns inward due to muscle imbalance.

**Why the Correct Answer is Right**
In paralytic convergent squint, diplopia is **crossed** or **uncrossed**, depending on which eye is fixating and which muscle is paralyzed. If the medial rectus is paralyzed, the eye cannot converge, but if the lateral rectus is paralyzed, the eye turns inward due to unopposed medial rectus action, leading to **uncrossed diplopia** when attempting to look outward.

**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect as it doesn't specify the type of diplopia.
**Option B:** Incorrect because the type of diplopia isn't clearly linked to paralytic convergent squint.
**Option C:** Incorrect as the specifics of the diplopia in this condition aren't detailed.
**Option D:** Incorrect without the context of which option is correct.

**Clinical Pearl / High-Yield Fact**
Remember, in paralytic squint, the image seen by the deviated eye is always **outside** the image seen by the fixating eye, helping to distinguish between different types of squint.

**Correct Answer:** D. Uncrossed.
