The Error class is a RuntimeException.

Any statement that can throw an Error must be enclosed in a try block.

Answer:

catch(X x) can catch subclasses of X where X is a subclass of Exception.

Solution:

Option "catch(X x) can catch subclasses of X where X is a subclass of Exception." is correct. If the class specified in the catch clause does have subclasses, any exception object that subclasses the specified class will be caught as well. Option B is wrong. The error class is a subclass of Throwable and not Runtime Exception. Option C is wrong. You do not catch this class of error. Option D is wrong. An exception can be thrown to the next method higher up the call stack.
