A. [11, 12, 13, 14, 15, 16, 17, 18, 19, 10, 20, 30, 40, 50, 60, 70, 80, 90]
B. [10, 20, 30, 40, 50, 60, 70, 80, 90]
C. [11, 12, 13, 14, 15, 16, 17, 18, 19]
D. [0, 10, 20, 30, 40, 50, 60, 70, 80]

Solution

A. [11, 12, 13, 14, 15, 16, 17, 18, 19, 10, 20, 30, 40, 50, 60, 70, 80, 90]

Explanation

The code shown above adds 10 to each element of the matrix and prints the output row-wise. Since the list l already contains some elements, the new elements are appended to it. Hence the output of this code is: [11, 12, 13, 14, 15, 16, 17, 18, 19, 10, 20, 30, 40, 50, 60, 70, 80, 90].
