Geologists found fossils of similar marsupials from the same time period across south america, africa, antarctica, india and australia. what theory is supported by this discovery?
those continents were once a part of one supercontinent.
a vast land bridge once connected those continents.
early marsupials were strong swimmers.
the processes happening today are the same processes that have occurred in the past.

A. Those continents were once a part of one supercontinent.

Explanation:

This so called supercontinent is called Pangea, which existed during the late Paleozoic and early Mesozoic eras, and assembled approximately 335 million years ago, which began to break apart about 175 million years ago.

Option (1)

Explanation:

The marsupials are the mammals that belong to the mammalian infraclass, commonly known as the Marsupialia. They are characterized by the presence of a pouch on their body that enables them to carry their young ones. Most of the present-day marsupials are found in America and Australia. For example, kangaroos and possums,

These marsupial fossils are found in the rocks of most of the continents namely South America, Africa, Antarctica, India, and Australia. These fossils were dated and found to be of similar age. These data (evidence) helped in supporting the theory of continental drift that describes that the continents were once all together, and were separated about 250 million years back due to the plate tectonic activities.

Hence, the correct answer is option (1).

i think the answer is b.
