This ocean rim is called the "ring of fire" because of the several volcanoes and other tectonic activities present there.
a: atlantic ocean
b: pacific ocean
c: indian ocean
d: arctic ocean
e: antarctic ocean

Option (B)

Explanation:

The "Ring of Fire" is the oceanic rim formed along the boundary of the pacific ocean where a high number of earthquakes and eruptions of volcanoes take place. The shape of this ring resembles a horse-shoe and the areas that are located in and around this location are prone to the significant number of earthquakes and volcanism. This ring is about 40,000 km long and has formed due to the subduction of the Pacific plate under the Indo-Australian plate, North American and South American plate. It is a convergent plate boundary marked by the presence of deep-sea trenches and volcanic island arcs.

Due to this continuous plate collision along this boundary, tectonic activities are very frequent.

Thus, the correct answer is option (B).

explanation:

the fossil record extends back to a dog-like ancestor some 55 million years ago, which gave rise to the first horse-like species 55 to 42 million years ago in the genus eohippus.

the answer would be 3
