The <em>correct answer</em> is:
The 4's row.
Explanation:
The even rows in a the multiplication chart are the 2's, 4's, 6's, 8's, 10's, and 12's.
In the 2's row, we have: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24. Looking at the ones digits, we do not have the correct pattern.
In the 4's row, we have: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48. This is the correct pattern (starting with 4): 4, 8, 2, 6, 0, 4, 8, 2, 6, etc. This is the correct row.
