Mutual recursion occurs when two or more functions call each other, creating a loop of calls. In option II, method E calls method T, which calls method F, which in turn calls method E, forming a mutual recursion. Options I and III do not represent mutual recursion; I is a simple chain of calls without looping back, and III is an example of direct recursion, not mutual recursion.
