True. Many of these
stones have been exposed to the elements.
Eventually such an exposure would wear out these stones as some of its
parts will start to chip away. More it
is exposed to the elements, the more it gets affected. The result is a strange shape due to the
exposure.
The correct answer is - c. sunlight.
The sunlight, or rather lack of it, is the biggest limiting factor for growth on the floor of the rainforests. The dense canopies of the higher trees block the sunlight to reach the floor of the rainforest, thus the plants growing in the shades are much smaller, have become specialized for life without or with very little sunlight. They are not able to compete with the trees that are very high to reach the upper parts of the forest and get direct sunlight, so they are on the floor, in the shades. In fact these plants have become so specialized to life without sunlight that if the big trees are removed and they are exposed to the sun they will not manage to survive.
