Solution

The correct option is C
WOIM
  • WORD → DOID
  • PROM → KRLM
Letters in even places are the same, while letters in odd places are the opposite of the original letter (W is the 23rd letter in alphabetical order and D is 23rd in reverse alphabetical order. Similarly, R is the 18th letter in alphabetical order, while I is the 18th letter in reverse alphabetical order).

The second and last letters will be O, and M itself. D (the first letter of DORM) is the 4th letter in alphabetical order, and hence, the first letter in the coded form will be 4th letter in reverse alphabetical order → W So,
  • DORM → WOIM is the correct code.
  • WORD → DOID
  • PROM → KRLM
सम स्थानों पर अक्षर समान हैं, जबकि विषम स्थानों के अक्षर मूल अक्षर के विपरीत हैं (W वर्णमाला क्रम में 23 वां अक्षर है और D उल्टे वर्णमाला क्रम में 23 वां अक्षर है। इसी तरह, R वर्णमाला क्रम में में 18 वां अक्षर है, जबकि I उल्टे वर्णमाला क्रम में 18 वां अक्षर है)।

दूसरा और अंतिम अक्षर O और M होगा। D (DORM का पहला अक्षर) वर्णमाला क्रम में चौथा अक्षर है, और इसलिए, कोडित रूप में पहला अक्षर, उल्टे वर्णमाला क्रम का चौथा अक्षर W होगा।
  • अतः, DORM → WOIM सही कूट है
