Re: Which of the following propositions is true
So (a) is your choice? Can you give your rationale for choosing that one? Or, why do you think the other choices are not correct?

Re: Which of the following propositions is true
The word "must" is usually a disqualifier in statements like these, especially in Java. Considering that (a) is true, what single class must every Java class extend?
(b) - Focusing on the word "must" again, is there a single interface that Java classes must extend? Do classes extend interfaces?
(c) - No "must" here, but what else is wrong with the statement?
(d) - Similar to (b), is there a single interface that Java classes must implement?
