According this graph which statements is most appropriate ;

a) The air surrounding the leaf is very still, the layer of unstirred air on the surface of the leaf may be so thick that it is the primary deterrent to water vapor loss from the leaf   

b) The air surrounding the leaf is very still, reduces the thickness of the boundary layer at the leaf surface, reducing the resistance of this layer

c) The moving air reduces the thickness of the boundary layer at the leaf surface, reducing the resistance of this layer    

d) The moving air, the layer of unstirred air on the surface of the leaf may be so thick that it is the primary deterrent to water vapor loss from the leaf
