Solution

The correct way to declare a constant variable in Java is:

a. final int PI = 3.14;

In Java, the 'final' keyword is used to declare a constant variable. Once a final variable has been assigned, it always contains the same value. If a final variable holds a reference to an object, then the state of the object may be changed by operations on the object, but the variable will always refer to the same object. This applies also to arrays, because arrays are objects; if a final variable holds a reference to an array, then the components of the array may be changed by operations on the array, but the variable will always refer to the same array.
