To read the matrix, the first digit represent the row, and the second digit represent the column.

For example. 43 will represent row 4 column 3 , which is the letter "I"

Note that row 0 to 4 are in the first box and row 5 to 9 are in the second box.

Try Option A:

23 = row 2 column 3 = R

66 = row 6 column 6 = E

01 = row 0 column 1 = T

02 = row 0 column 2 = N

⇒ Option 1 is NOT the answer

Try Option 2 :

43 = row 4 column 3 = T

11 = Row 1 column 1 = I

55 = Row 5 column 5 = M

66 = Row 6 column 6 = E

⇒ Option 2 is  the answer

Answer: (2)  43, 11, 55, 66
