What would happen if you try to use an uninitialized object reference?

Compilation error

NullPointerException

If you try to use an uninitialized object reference, you will receive a NullPointerException. This means that you tried to access an object that does not exist or has not been created yet. Option A is incorrect because a compilation error occurs when there is a mistake in the code itself, such as a syntax error. Option C is incorrect because an uninitialized object reference does not automatically get initialized to a new object. Option D is incorrect because it is not a valid operation to use an uninitialized object reference.
