Answer
Exam answer
(i) Big data (ii) 4
Explanation
(i) Counting from 0: x[0] is "Artificial intelligence", x[1] is "IOT", x[2] is "Machine learning", x[3] is "Big data". (ii) x.length is the number of ELEMENTS in the array, which is 4. Note it is written without brackets, because length is a variable of the array, not a method. The contrast being tested: x.length is 4, but x[3].length() would be 8 — the number of characters in "Big data". Array length has no brackets; String length() has them.
