Read the given statements and select the correct option
Statement 1 : The rainwater in mountains flows away down the slopes, leaving very little water for the trees to absorb
Statement 2 : To conserve water, the leaves of the pine trees are needle-like to reduce the loss of water due to evaporation.

A Both statements 1 and 2 are true and statement 2 is the correct explanation of statement 1.
B Both statements 1 and 2 are true but statement 2 is not the correct explanation of statement 1.
C Statement 1 is true and statement 2 is false.

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.
