Answer
Exam answer
(d) ar.length-1.
Explanation
Two things are being tested at once. First, an array uses length as a variable with no brackets (ar.length); it is String that uses the method length(). Second, since indices start at 0, an array of n elements has its last element at index n-1. Both together give ar.length-1.
In words
ar.length-1.
