Answer:

Each object of this class has its own copy of GREETING

Explanation:

option c: Each object of this class has it’s own copy of GREETING

This is the only false statement. When a variable is preceded by the Static key word only one copy of that variable is created, no matter the amount of object created from the instance of that class.

option a: Each object of this class can access GREETING, this is true.

option b: The value of GREETING can’t be changed in any methods, this is true because GREETING is preceded by the keyword final.

option d: GREETING.length() = 2, this is true because the method length() is use to get the length of the string "Hi" which is 2.

option e: GREETING.toUpperCase() = "HI", this is also true because the method toUpperCase() convert all the character of "Hi" to uppercase.

Note: All these are peculiar to java programming language.

In the program, the two instances of the class are created, incrementing the counter variable to two, the print statement outputs 2 as the result of the program.
