Answer:
A rebuttable presumption is assumed true until a person proves otherwise (for example the presumption of innocence). In contrast, a conclusive (or irrebuttable) presumption cannot be refuted in any case (such as defense of infancy in some legal systems).Explanation:
Rebuttable presumption: Both in common law and in civil law, a rebuttable presumption is an assumption made by a court that is taken to be true unless someone comes forward to contest it and prove otherwise.
For Example
a defendant in a criminal case is presumed innocent until proved guilty.
