If a conservation plan only builds fencing but does not protect water sources, what will be lacking?

Correct answer: Protection of basic life needs of organisms will remain incomplete

The direct answer is B: Protection of the basic life needs of organisms will remain incomplete. Conservation means protecting wildlife and the habitat that supports it. A habitat needs suitable food, water, shelter and space. Fencing can reduce entry, disturbance or some human-wildlife conflict, but it cannot provide drinking water or restore a missing water source. First, animals need water to drink and plants need it to grow. Second, water supports insects, fish and other parts of the food web. Third, food and shelter are also needed, so fencing alone is not a complete plan. Option A is not the main ecological deficiency; beauty is not the basic requirement being tested. C is wrong because fencing does not automatically increase hunting; it may even help control access. D is an unsupported exaggeration: animals do not all move to cities. Memory cue: habitat protection means food, water, shelter and space together.
