    1. DCBA
    2. BCAD
    3. CADB
    4. BDCA

 

  • Correct Answer
    Choice D. BDCA

Detailed Solution

Sentences B and D talk of flowers and flowering plants. Sentence B talks of how land plants existed without flowers for several millions of years. Sentence D talks of when flowering plants appeared. It is clear D follows B.

Sentence C speaks of “equally familiar grasses”. So obviously, some other example- in this case, flowering plants- precedes this.

Sentences A and C talk of the evolution of grasses. A follows C.

So we have the correct order of arrangement as 4) BDCA

Correct Answer: BDCA
