Concept:Desert plants have special adaptations to survive dry conditions, like long roots and reduced leaves. The Desert Oak is one such plant.
Explanation:Statement A says it is found in deserts of Abu Dhabi, but the Desert Oak is native to Australia, not Abu Dhabi. So A is false.
Statement B says it grows about 4 metres tall, which matches the height of a classroom. This is true for a young Desert Oak.
Statement C says its roots go deep to reach water. This adaptation helps it survive. So C is true.
Statement D says the root length equals 50 such trees laid end to end, meaning about 200 metres. Desert Oak roots are long but not that long. So D is false.
Statement E says it has very few leaves. This is true as it reduces water loss.
Thus, the true statements are B, C, and E.
Answer:C. B, C and E
