If BAPTISM is coded as DCRVKUO by shifting each letter two places forward in the alphabet, then using the same rule, how will the word TIN be coded?

Introduction / Context:
This question involves a simple letter shifting code. The word BAPTISM is transformed into DCRVKUO, which suggests that each letter has been moved a fixed number of positions forward in the alphabet. Once we determine this shift, we can apply the same shift to the letters of TIN to obtain its coded form. Such Caesar style shifts are very common in coding decoding questions.

Given Data / Assumptions:
- BAPTISM is coded as DCRVKUO.
- We must find the code for TIN using the same pattern.
- The mapping is letter to letter with no change in word length.

Concept / Approach:
The method is to examine one or more letter pairs from the given example and compute how many positions forward in the alphabet each letter has moved. If the same shift is found for all letters, then we have a uniform shift code. Afterward, we apply this uniform shift to each letter in TIN. If any wraparound from Z back to A were needed, we would handle it, but in this case, the letters remain within the standard range.

Step-by-Step Solution:
Step 1: Match letters from BAPTISM → DCRVKUO. B → D, A → C, P → R, T → V, I → K, S → U, M → O. Step 2: Compute the shift for B → D. B is 2nd letter, D is 4th, so the shift is +2. Step 3: For A → C, the shift is again +2 (1 to 3). P → R is +2 (16 to 18), T → V is +2 (20 to 22), I → K is +2 (9 to 11), S → U is +2 (19 to 21), and M → O is +2 (13 to 15). Step 4: Since every letter is shifted by +2, we apply the same rule to TIN. Step 5: T is 20th, so T + 2 gives V (22nd). I is 9th, so I + 2 gives K (11th). N is 14th, so N + 2 gives P (16th). Hence, TIN is coded as VKP.

Verification / Alternative check:
We have verified that the shift is consistently +2 for all letters of BAPTISM, making it a standard Caesar shift. No alternating pattern or position dependent shift is required to explain the given code. Therefore, shifting each letter of TIN by +2 is the simplest and correct application of the rule, resulting in VKP.

Why Other Options Are Wrong:
- Option EBC reflects a different pattern that does not correspond to a uniform +2 shift from TIN.
- Option FDF does not match the letter positions that result from adding 2 to T, I, and N.
- Option CLS would require irregular shifts and is not consistent with the code used for BAPTISM.

Common Pitfalls:
Sometimes learners mistakenly use a -2 shift or mix forward and backward shifts without verifying all letter pairs. Others may guess codes that form meaningful words in English but do not respect the given pattern. The correct strategy is to rely on consistent positional changes, not on whether the resulting code itself is a real word.

Final Answer:
Using a uniform shift of two positions forward in the alphabet, the word TIN is coded as VKP.
