In which areas is VND commonly found?

Viral Neuropathogenic Disease (VND) can indeed be found in various global locations, which makes the response highlighting its worldwide presence correct. This disease does not restrict itself to a specific geographic area or climate zone, as seen with some other illnesses. Instead, it can occur in different environments, though it may be more prevalent in certain regions due to factors like agricultural practices, vector presence, and the types of livestock raised.

This answer stands out as the proper choice because it acknowledges the extensive range of environments where VND can manifest, unlike some of the other options which suggest limitations based on geography or specific settings. For example, while it may be often observed in Asia due to certain agricultural practices, it can also be affected by global transport of animals and products, leading to occurrences in diverse areas. Furthermore, suggesting that it is found "only in tropical regions" or "in farms only" restricts the understanding of its potential spread and adaptation in various ecosystems.
