Which type of scientific statement is defined as a statement of fact that is generally accepted to be true and universal because it has always been observed to be true? theory probability law hypothesis

A law is a scientific statement which is defined as a statement of fact and is generally accepted to be true or universal because it has always been observed to be true.

Explanation:

Among the options it is only a law that is accepted to be universal. An observation becomes accepted as a law after several years of experiments. It has to prove itself to be universal which means it can be accepted as such in any part of the world at any point of time.

A theory is just the best possible explanation of a fact and it can be replaced when a better explanation comes in its place. Thus there is no surety about the longevity of a theory.

Probability is just a chance of an observation and thus it is not universal. A hypothesis also cannot be considered universal because it is also just an explanation usually proposed with not many evidences.
