In the word HYPNOTIC, each letter of the word is changed to the letter immediately succeeding it in the English alphabetical order and then the new group of letters thus formed is rearranged according to the English alphabetical order. Which letter is second to the left in the new rearranged group of letters?
I
O
D
J
I
Map each letter to its successor immediately, then identify the smallest letters to determine the sequence order without fully writing every letter if not needed.

Transform letters to their successors
Original letters: H, Y, P, N, O, T, I, C. Successors (+1 position): H тЖТ I, Y тЖТ Z, P тЖТ Q, N тЖТ O, O тЖТ P, T тЖТ U, I тЖТ J, C тЖТ D. New group: I, Z, Q, O, P, U, J, D.
Rearrange alphabetically
List the letters: I, Z, Q, O, P, U, J, D. Alphabetical order: D, I, J, O, P, Q, U, Z.
Locate the second letter from the left
In the ordered sequence D, I, J, O, P, Q, U, Z, the first letter is D and the second letter is I.
B: O is the 4th letter in the sequence. C: D is the 1st letter in the sequence. D: J is the 3rd letter in the sequence.
A is correct because after shifting each letter by +1 and rearranging (D, I, J, O, P, Q, U, Z), the letter at the second position from the left is I.
When asked for a specific position after rearrangement, do not waste time rewriting the entire word; list the letters and sort only the first few to identify the position quickly.
