Consider a local variable x bound to a reference type value, in the following assignment statement: y - f(x) Is it possible for the value x references to change as a result of evaluating this assignment statement? O No, because there will be a separate, distinct copy of x 's value in the corresponding parameter of f's frame O No, only y 's value may change as it is the left-hand side of the assignment operator O No, but for reasons not specified above O Yes, because f could reassign a new value to be bound to x O Yes, because f receives a parameter referencing the same value as x O Yes, but for reasons not specified above

Question
Consider a local variable x bound to a reference type value, in the following assignment
statement:
y = f(x)
Is it possible for the value x references to change as a result of evaluating this assignment
statement?
O No, because there will be a separate, distinct copy of x's value in the corresponding
parameter of f 's frame
O No, only y 's value may change as it is the left-hand side of the assignment operator
O No, but for reasons not specified above
O Yes, because f could reassign a new value to be bound to x
O Yes, because f receives a parameter referencing the same value as x
O Yes, but for reasons not specified above
