leaves of pine trees are needle like so that snow falls easily and do not collect on the leaves so i think the answer is wrong

Ans b As less water is absorbed by soil so there is scarcity of water. Leaves of pine trees are modified to spines as the surface area of needle like leaves is much less than normal leaves and less transpiration is done by them. In that way pine trees save water.
