Read the following statements given below: a. The Bhangar soils are older Alluvium. b. The Bhangar soils are frequently inundated. c. The Bhangar soils are rich in concentration and nodules. d. The drier areas of Bhangar soils exhibit saline and alkaline efflorescence. Select the correct option:
a, c and d are true
Bhangar is older alluvium on terraces above the active floodplain, so it is not frequently inundated. It commonly contains calcium-carbonate concretions called kankar, and dry areas may show saline or alkaline surface deposits. Thus a, c and d are true; b is false.

Select the correct answer using the code given below.
“Leaf litter decomposes faster than in any other biome and as a result the soil surface is often almost bare. Apart from trees, the vegetation is largely composed of plant forms that reach up into the canopy vicariously, by climbing the trees or growing as epiphytes, rooted on the upper branches of trees.” This is the most likely description of
