The correct answer is: A. tall dense forests of broad leaf trees.
In the tropical wet climate zone we can find the tropical rainforests. In this climate zone, the flora is represented by very tall trees, that are very close to one another, thus making up a very dense and tall forest, with thousands of other smaller plants occupying the lower levels of the rainforests. These trees have very broad leaves, and they are also green throughout the whole year, as it is always summer. The reason why these forests are so tall is that the trees are very abundant and they are competing for the sunlight, and in order to get to some sunlight in these forests, a tree has to be very tall and to outgrow the competition.
