Step 1: Understanding the Concept:
The three items in Column I come from the chapter on Resources and Development. They deal with how we share, plan and use resources wisely.
We match each item with the statement in Column II that explains its meaning.
Step 2: Match item 1: Equitable distribution of resources:
Equitable distribution means every person gets a fair share of resources. Gandhiji said that the earth has enough for everyone's need but not for one person's greed.
Greed leads to the pile-up of resources in a few hands. So equitable distribution prevents concentration of resources in a few hands. This is Y.
Step 3: Match item 2: Sustainable existence:
Sustainable existence means living in a way that does not destroy the resource base. Life continues for all living things, for now and for the future.
So it ensures long-term survival of all life forms. This is X.
Step 4: Match item 3: Resource planning:
Resource planning is the wise use of resources. A planner has to meet the needs of development today and also keep enough resources for coming generations.
So it balances current development with conservation for the future. This is Z.
Step 5: Check the options:
We have 1-Y, 2-X, 3-Z. Only option A has this exact set.
Option B (1-Z, 2-Y, 3-X) gets all three wrong. Option C (1-X, 2-Z, 3-Y) also gets all three wrong.
Option D (1-Y, 2-Z, 3-X) gets item 1 right, but item 2 and item 3 are swapped, so it is wrong.
Final Answer:
The correct match is 1-Y, 2-X, 3-Z, option A.
\[ \boxed{\text{A. 1-Y, 2-X, 3-Z}} \]
