Which letter is first to the right in the new rearranged group of letters?

Apply the successive shift (+1) to each letter of DYNAMIC first, then arrange the resulting letters in alphabetical order to find the first letter from the right.
Step 1: Apply Successive Letter Shift (+1)
Each letter in DYNAMIC is changed to the letter immediately succeeding it (+1 in alphabetical order): D тЖТ E, Y тЖТ Z, N тЖТ O, A тЖТ B, M тЖТ N, I тЖТ J, C тЖТ D. The new group of letters is E, Z, O, B, N, J, D.
Step 2: Rearrange in English Alphabetical Order
Sorting the new group of letters (E, Z, O, B, N, J, D) alphabetically yields: B, D, D, E, J, N, Z.
Step 3: Identify the First Letter to the Right
In the rearranged alphabetical sequence (B, D, D, E, J, N, Z), the last letter on the right (which is first when counting from the right end) is Z.
A: E is incorrect as it is the 4th letter from the left and 4th from the right. B: D is incorrect as it appears twice at positions 2 and 3 from the left. C: B is incorrect because it is the first letter from the left, not the right.
D is correct because the rearranged group of letters is B, D, D, E, J, N, Z, and the first letter to the right (end of the sequence) is Z.
Always double-check whether the question asks for the position from the left or the right end after rearrangement to avoid silly mistakes.
