Read the following statements in the context of Laws and theories in Science :

S1 : Laws are generalisation statement whereas theories are explanations.

S2 : Laws are very old and theories are contemporary.

S3 : Laws can’t be changed whereas theories are subject to change.

The correct option is S1 is true; S2 and S3 are false.

Let us analyze each statement step-by-step to understand the nature of scientific laws and theories:

Analysis of Statement 1 (S1):
Scientific laws describe what happens in nature under specific conditions; they are generalizations or descriptive summaries based on repeated empirical observations. Scientific theories, on the other hand, explain why or how these natural phenomena occur by integrating multiple hypotheses, laws, and evidence. Therefore, S1 is true.

Analysis of Statement 2 (S2):
Both laws and theories are fundamental components of science that have been developed throughout history and continue to be proposed and refined today. Theories are not strictly "contemporary," nor are laws exclusively "very old." Both evolve as new evidence emerges. Therefore, S2 is false.

Analysis of Statement 3 (S3):
All scientific knowledge, including both laws and theories, is tentative and subject to modification, refinement, or rejection if new experimental evidence contradicts it. Neither laws nor theories are absolute or immune to change. Therefore, S3 is false.

Conclusion: Statement S1 is correct, while statements S2 and S3 are incorrect.
