The code for outside is either WD or ZS. Hence, (c).

12)In each of the following below is given a group of letters/digits followed by four combinations of letters/symbols numbered (a), (b), (c) and (d). You have to find out which of the combinations correctly represents the group of letters based on the following coding system and mark the number of that combination as the answer. If all the four are not correct then mark (e) as the answer.

Conditions:
I. If second letter is consonant and first letter is vowel then both are coded with the code of the vowel.
II. If both the second and the second last letter of the group are consonants, their codes are to be interchanged.
III. If both second digit and the fourth digit of the group is a prime number, both are to be coded as the code for the second digit.
IV. If last digit of the group is even number then it will be coded as code of first element.
