If you want only one memory location to be reserved for a class variable, no matter how many objects are instantiated, you should declare the variable as________

dynamic
unary
static
volatile

The correct answer is C. static.

A static variable is a variable that is associated with a class, not with an instance of a class. This means that there is only one copy of the variable, no matter how many objects are instantiated from the class.

A dynamic variable is a variable that is created on the heap, and its lifetime is managed by the garbage collector.

A unary operator is an operator that takes one operand.

A volatile variable is a variable whose value can be changed by code outside of the current thread.

Here is an example of a static variable:

“`class MyClass {
static int x;

public MyClass() {
    x = 10;
}

}
“`

In this example, the variable x is a static variable. This means that there is only one copy of the variable, no matter how many objects are instantiated from the class MyClass. The value of x will be 10 for all objects of the class MyClass.
