Identify the relationship between the first pair of letter clusters and select the option that shares the same pattern for the second pair.
PRISM : OSHTL :: TRACE : ?
Show answer & explanation
Correct answer: D
Explanation
The pattern followed in the given pair is an alternating shift of −1, +1, −1, +1, −1 on the positional values of the letters:
• P − 1 = O
• R + 1 = S
• I − 1 = H
• S + 1 = T
• M − 1 = L
Applying the same pattern to TRACE:
• T − 1 = S
• R + 1 = S
• A − 1 = Z
• C + 1 = D
• E − 1 = D
Thus, the required letter-cluster is SSZDD.
Therefore, the correct option is (D).
