A. [1, 5, 9]
B. [3, 5, 7]
C. [4, 5, 6]
D. [2, 5, 8]

Solution

A. [1, 5, 9]

Explanation

We can also perform tasks like pulling out a diagonal. The expression shown above uses range to generate the list of offsets and the indices with the row and column the same, picking out A[0][0], then A[1][1] and so on. Hence the output of the code is: [1, 5, 9].
