Answer 1

##### Answer and Explanation #####

Question - 2- The INCORRECT OPTION is C i.e. Thorny leaf edges, flammable oils.

( Because "Thorny leaf edges, flammable oils." it reveals that hervivory of the plants can be reduced by these adaptation. )

Explanation- "A. Havily extensively spreading root systems" reveals that Plant have to develop their root system so that they can absorb more and more water.

"B. Small leaves, hairs on leaves" Plants have to protect the leaves from the sun light, so they have to have a small leaf area change their position to avoid sunlight because more sunlight more temperature resulting more transpiration and water loss. But in some plants plants adapt light colour of leaves or hairy leaves.
