Solution :
Given:
1. CROW ⇒ 6970
2. ORCA ⇒ 7569
By comparing the coded words, we find that –
In words 1 and 2, the common letters are C, R, and O, and the common codes are 6, 9, and 7.
The remaining letters and code in word 1 are W and 0 and in word 2 are A and 5.
Finally, W→0; A→5; C/R/O→6/9/7
So, the code for W is 0 in the code language. Hence, the fourth option is correct.
