T→66, 67, 68, 88
R→11, 23, 34, 43
A→55, 76, 79, 87, 99
I→13, 21, 30
N→56, 78, 89
First option:
12, 88, 43, 76, 21, 78; All the letters of the word STRAIN can be represented through this option.
Second option:
87, 66, 11, 79, 13, 33; S and N cannot be represented as 87 and 33 respectively.
Third option:
32, 68, 43, 85, 97, 54; A, I, and N cannot be represented as 85, 97, and 54 respectively.
Fourth option:
02, 65, 97, 34, 79, 44; T, R, A, I, and N cannot be represented as 65, 97, 34, 79, and 44 respectively.
So, STRAIN can be represented using the codes 12, 88, 43, 76, 21, 78. Hence, the first option is correct.
