What is the meaning of the word "presumption"?

The term "presumption" refers to an idea or belief that is accepted as true without proof. It often arises when something is assumed or taken for granted based on existing knowledge or experience. In this context, "A belief based on assumed truth" accurately captures the essence of what a presumption entails. It indicates that the belief does not require solid evidence and is instead founded on an assumption, which aligns perfectly with the definition of presumption in both everyday language and legal contexts.

The other options do not align with the meaning of "presumption." A proven fact is something that has been established through empirical evidence or verification, which directly contradicts the idea of a presumption being based on assumption. Evidence-based theory suggests a conclusion drawn from verifiable data, which again is more rigorous than a presumption. Lastly, a logical conclusion implies a reasoned outcome derived from premises, whereas a presumption lacks this level of justification and certainty.
