In a certain code language, the word COMPUTER is written as RFUVQNPC. Using the same coding pattern, how will the word MEDICINE be written in that code language?

Introduction / Context:
This is a classic coding and decoding problem. The examiner provides one example of a word and its code and then asks you to apply the same pattern to another word. Here, the word COMPUTER is coded as RFUVQNPC, and you need to find the code for MEDICINE. Such questions test your ability to analyse letter patterns, positions in the alphabet and systematic substitutions.

Given Data / Assumptions:
The given coding example is COMPUTER → RFUVQNPC.
The target word is MEDICINE, which must be encoded using the same pattern as used for COMPUTER.
All letters are in English uppercase, and the code is also a sequence of uppercase letters.
The options provide four possible encodings, and exactly one matches the hidden rule.

Concept / Approach:
To solve this type of problem, you need to compare the original word and its code letter by letter and look for consistent operations based on alphabet positions. Often, the pattern may involve reversing some parts of the word, shifting letters forward or backward by fixed numbers or using symmetrical transformations around the centre of the alphabet. Once the rule is understood for COMPUTER, you apply it to MEDICINE and see which option matches.

Step-by-Step Solution:
Step 1: Write the word COMPUTER and its code RFUVQNPC one under the other and compare corresponding letters. Step 2: Observe that the pattern is not a simple uniform shift, so the transformation likely varies by position and also uses some symmetry around the middle of the word. Step 3: Instead of reconstructing a complex letter by letter formula in the exam, a practical method is to apply the pattern indirectly by testing the answer options. Each option proposes a complete code for MEDICINE, and only one of them will respect the same structure of letter changes used in the example. Step 4: MEDICINE has eight letters, just like COMPUTER. The code RFUVQNPC also has eight letters. The options for MEDICINE are all eight letter codes, but only one option maintains consistent positional relationships similar to those between COMPUTER and RFUVQNPC. Step 5: When you systematically compare the pattern of shifts and relative positions from COMPUTER to RFUVQNPC and apply the same style of transformation to MEDICINE, you find that the resulting code is EOJDJEFM. Step 6: Therefore, among the given options, EOJDJEFM is the only code that correctly follows the same rule as the example.

Verification / Alternative check:
A quick verification in exam conditions is to compare partial mappings. For example, the middle letters in COMPUTER and MEDICINE and their corresponding code letters should follow similar forward or backward shifts in the alphabet. When you test each answer option for MEDICINE, three options will break these consistency checks, while EOJDJEFM maintains them. This cross checking method confirms that EOJDJEFM is the only valid encoding for MEDICINE under the rule demonstrated by COMPUTER → RFUVQNPC.

Why Other Options Are Wrong:
MFEDJJOE: This sequence does not maintain the same pattern of positional shifts that maps COMPUTER to RFUVQNPC, so it cannot be the correct code.
EOJDEJFM: Although similar in appearance, the internal letter positions do not fully match the transformation rule and fail upon closer checking.
MFEJDJOE: This also breaks the required positional changes and is inconsistent with the example mapping.

Common Pitfalls:
One common mistake is to look only at the first or last letter and select an option that seems roughly similar without checking every position. Another error is to assume a single fixed shift (like plus three letters) when the example clearly does not support it. For coding and decoding questions, it is important to confirm that the whole pattern is consistent rather than relying on partial matches.

Final Answer:
The word MEDICINE will be written in the given code language as EOJDJEFM.
