Explanation:

C. To create or set an object to null, the null keyword can be used. Objects are also set to null when they are declared but not yet initialized.

A, B, and D are incorrect.

A is incorrect because when the new keyword is used, it initializes the object to a new non-null object.

B is incorrect for the same reason as A, plus the Object constructor does not accept any arguments.

D is incorrect because null() is a made up method and is invalid in Java.
