Read the given passage and answer the questions that follow.
The polar regions are covered with snow. There may also be snowfall in mountain regions during the winter. The trees growing on mountains are cone-shaped, with sloping branches. Many of them, such as pine, have sharp needle-like leaves. Animals living on mountains have thick skin or fur to protect themselves from cold, e.g., yaks and snow leopards.
Why do pines have sharp needle-like leaves?

A This reduces loss of water due to transpiration.
B This reduces chances of catching forest fire.
C This helps the snow to slide-off easily.
D This allows branches to carry loads of snow.
