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

Option C will not compile; the synchronized modifier applies only to methods. Option A and B will compile because protected and transient are legal variable modifiers. Option D will compile because volatile is a proper variable modifier.
