Process of elimination

Process of elimination is a logical method to identify an entity of interest among several ones by excluding all other entities. In educational testing, it is a process of deleting options in which the possibility of an option being correct is close to zero or significantly lower than that of other options. This version of the process does not guarantee success, even if only one option remains, since it eliminates possibilities merely on the grounds that they are improbable. The process of elimination can only narrow down the possibilities; thus, if the correct option is not among the known options, it will not arrive at the truth.
