Final answer:
The equality of two reference variables can result in true or false, as it depends on whether they point to the same instance.
Step-by-step explanation:
The direct answer to the question is: C. may be true or false.When dealing with two reference variables, such as t1 and t2, the equality t1 == t2 checks whether the two references point to the exact same object or not. If t2 is true, it indicates that t2 does indeed point to an object; however, whether t1 points to the same object cannot be determined without further context. Therefore, t1 == t2 may be true or false depending on if they point to the same instance.
The direct answer to the question:C. may be true or falseExplanation:The expression t1 == t2 compares the values of the reference variables t1 and t2. If t2 is true, it does not necessarily mean that t1 and t2 have the same value. Therefore, the result of t1 == t2 can be either true or false, depending on the actual values of t1 and t2.
