Select the correct answer using the codes given below:

• A. 1 only
• B. 2 only
• C. 2 and 3 only
• D. 1, 2 and 3

Answer 1

The correct option is D 1, 2 and 3

Explanation:

All the Statements are correct:
Geological “fit” evidence is the matching of the coastlines of South America and West Africa.
The fossil relevance: Examples of fossils found on separate continents and in no other regions indicate that these continents were once joined together because the oceans between the landmasses acted as a barrier for fossil transfer i.e. Mesosaurus, Cynognathus and Glossopteris.
Rock deposits and Grooves left by ancient glaciers are found in different continents near the equator. This indicates that the glaciers either formed in the mid of the ocean and/or covered most area of the Earth.
