Call-By-Value

A method of parameter passing in programming where a copy of the actual parameter's value is made and passed to the function, protecting the original value from modification.

Primitive Types

Basic data types built into the language that include int, char, float, and boolean, among others.

Final Answer :
B
Explanation :
In Java, call-by-value is used with primitive types only. When a primitive type is passed as an argument to a method, a copy of the value is made and passed to the method. Any changes made to the parameter within the method do not affect the original value of the argument outside the method. This is different from call-by-reference, where the address of the argument is passed, allowing changes made within the method to affect the original value of the argument outside the method. However, in Java, objects are passed by reference, so changes made to the object within the method affect the original object outside the method.
