**Core Concept**
The question is likely referring to a disease that has a widespread distribution across the globe, transcending geographical boundaries. This disease could be caused by a variety of factors, including infectious agents, environmental exposures, or genetic predispositions.

**Why the Correct Answer is Right**
The correct answer is likely a disease that is caused by a ubiquitous pathogen, such as a virus or bacteria, which is capable of infecting humans across different populations and geographical regions. This disease may also have a high transmission rate, contributing to its global spread.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it is a disease that is primarily confined to a specific geographical region or population. For example, Lassa fever is primarily found in West Africa.

**Option B:** This option is incorrect because it is a disease that is caused by a vector-borne pathogen, which has a limited geographical range and is not found worldwide.

**Option C:** This option is incorrect because it is a disease that is primarily caused by a genetic or congenital factor, rather than an infectious agent.

**Clinical Pearl / High-Yield Fact**
One high-yield fact about diseases that are seen all over the world is that they often have a common underlying cause, such as a viral or bacterial pathogen, and require a coordinated global response for control and prevention.

**Correct Answer: D. Malaria**
