Correct option is D
The correct answer is: (d) Only A
Fact: A fact is an objective observation that can be verified and is independent of any interpretation or opinion. Facts are based on evidence and experience. For example, "The Earth revolves around the Sun" is a fact that has been confirmed through scientific observation and experimentation.
Law: A scientific law is a well-established principle that describes a phenomenon or relationship under certain conditions. Scientific laws are based on repeated observations and experiments, and they help us predict how things will behave under specific circumstances. For example, the law of gravity states that every object with mass attracts every other object with a force proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Key Differences:
Facts are specific observations, while laws are general principles that explain those observations.
Facts are independent of interpretation, while laws can involve some level of interpretation in their formulation.
So, statement A about facts being observations is correct, while statement B about laws being theories is not entirely accurate. Scientific theories are well-substantiated explanations of some aspect of the natural world, but they are not yet proven to be absolute truths. Laws, on the other hand, are based on confirmed evidence and have a high degree of predictive power.
