S1: Although all sources of energy ultimately come from natural processes, non-renewable resources cannot be replaced naturally at the rate they are being used. S6: The sustainable use of natural resources in a manner that provides the maximum benefit of these resources to humans over a period of time can be termed as conservation. P: This will increase the time and cost of mining and once these resources are used up they cannot be replaced. Q: Hence, we must remember that though our country is rich in mineral deposits these resources are short-lived. R: Extraction of these ores through the process of mining will soon become difficult and very expensive because these minerals have to be mined from greater depths over time. S: Mineral resources can be said to be finite and non-renewable.
A.QPRS
B.SPQR✓ Correct
C.SQRP
D.SQPR
Explanation
The logical sequence is S-P-Q-R. S1 introduces non-renewable resources. S states that mineral resources are finite and non-renewable, directly linking to S1. P follows by explaining the consequence — once used up they cannot be replaced. Q then concludes with 'Hence, we must remember' that India's mineral deposits are short-lived. R further elaborates that extraction will become difficult and expensive. S6 then provides the broader concept of conservation. Thus SPQR forms a coherent flow.
