A comet is a lump of rock and ice. Spacecraft have flown by comets. A comet only has a tail when it is near the sun. Most comets come from the Kuiper belt. A comet has actually been witnessed hitting a planet. Most comets have short orbital periods.
A comet is a tiny, frozen entity in the Solar System that heats up and starts to emit gases as it approaches the Sun. This process is known as outgassing. This results in an apparent atmosphere or coma, and occasionally a tail as well. These occurrences are caused by how the solar wind and solar radiation interact with the comet's nucleus.
The size of comet nuclei varies between a few hundred meters and tens of kilometers, and they are made up of loose clumps of ice, dust, and tiny rocky particles. A comet's orbit is typically very eccentric and elliptical, and its orbital period can range from a few years to possibly millions of years.

Answer:
The Himalayan Mountains by India, Nepal, and China are the best example of a convergent plate boundary.
Explanation:
The Himalayan Mountains are the highest mountain range in the world, but also the most massive one. It acts as a natural boundary between Southern, Southeastern, Eastern, Central, and Southwestern Asia. This mountain range is a relatively young one (geologically speaking), and it has formed because of the collision between the Indian and Eurasian tectonic plates.
When India diverged from Gondwana, it started to move toward Eurasia. After tens of millions of years, the Indian plate hit the Eurasian plate from the south, and with both of the plates being continental and having a boundary with their continental parts, they created a convergent plate boundary. The pressure between the plates has resulted in lifting up the crust, gradually creating a huge mountain range.
I would say D the Billingsella Corrugata, it IS in the oldest recorded time line, so by theory, it's the oldest (Don't quote me on that, I'm not %100)
