Coding and decoding reasoning – UGC NET Question

Statement A describes a common pattern where letters are shifted forward or backward in the alphabet. Statement B acknowledges that rearranging letters, such as reversing or swapping positions, may be part of the code. Statement C is correct because within a single question, the same underlying rule is normally applied to all examples. Statement D is false; coding puzzles are designed to follow a discoverable rule, not random changes, and E is false because different words usually get different codes according to the rule. Hence A, B and C only are correct, which is option C.

Option A:
Option A is incomplete since it omits C, thereby failing to mention the crucial examination principle that a single consistent rule governs all codes in one question.

Option B:
Option B is incorrect as it adds E, which wrongly suggests that knowing one code fixes all others, ignoring the dependence on the specific letters of each word.

Option C:
Option C is correct because it brings together the main transformation techniques and the idea of rule consistency, while excluding D and E, which mischaracterise coding questions as random or uniform across all words.

Option D:
Option D is wrong since it includes D, which asserts randomness, contradicting the logic-based nature of such questions, and it omits A, thus losing a central pattern used in letter coding.
