B
are in the same ocean
C

D
have similar types of rocks and fossils
Explanation: 

Detailed explanation-1: -One type of evidence that strongly supported the Theory of Continental Drift is the fossil record. Scientists have found fossils of similar types of plants and animals in rocks of similar age. These rocks were on the shores of different continents. This suggests that the continents were once joined.

Detailed explanation-2: -The evidence for continental drift included the fit of the continents; the distribution of ancient fossils, rocks, and mountain ranges; and the locations of ancient climatic zones.

Detailed explanation-3: -There are 2 main reasons geologists think the continents were once connected. One reason is that some coastlines share similar fossils. What is the other reason? South america and Africa, look like they are fitting together like a puzzle piece, sea floor spreading.

Detailed explanation-4: -Evidence. Two fossils in particular served as good evidence for the idea that the continents were once joined but have since separated: Glossopteris and Mesosaurus.

Detailed explanation-5: -Scientists have found that rocks on the east coast of South America are the same as rocks found on the west coast of Africa. These rocks are different from rocks found in other places on Earth, suggesting that the continents were once connected. Plant and animal fossils also reveal evidence.
