Option B is definitely wrong. The first element in the array is tab[0], not tab[1]. Rookie mistake!

This is a tricky one, but I think the correct answer is Option D. You have to initialize the array at the time of declaration, right?

Option C is correct. The expression tab[9] designates the last element in the array, since the index starts from 0.
