Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In Java, String objects use the length() method to return the character count, not a member variable. This is because String is a class - not a primitive or struct - so it encapsulates its data and exposes methods like length() rather than public fields. Option D's size() method doesn't exist for String.
