Best answer
The correct answer is (a) 431133

The best explanation: For encrypting using polybius square cipher we have to use the table which is shown below and write (row, col) coordinates corresponding to each letter.

1 2 3 4 5

1 A B C D E

2 F G H I/J K

3 L M N O P

4 Q R S T U

5 V W X Y Z

So the ciphered text will be “431133”.
