Select the option that is related to the third term in the same way as the second term is related to the first term.
FRONTIER : GSNOUHDS :: CLOSING : ?

The correct answer is DMNTHOH.

To solve this analogy, we need to determine the relationship between the first term (FRONTIER) and the second term (GSNOUHDS) and apply the same logic to the third term (CLOSING).

Let's analyze the pattern by looking at how each letter of FRONTIER is transformed into GSNOUHDS:
• F (Consonant) → F + 1 = G
• R (Consonant) → R + 1 = S
• O (Vowel) → O - 1 = N
• N (Consonant) → N + 1 = O
• T (Consonant) → T + 1 = U
• I (Vowel) → I - 1 = H
• E (Vowel) → E - 1 = D
• R (Consonant) → R + 1 = S

From this pattern, we can establish the rule:
• If the letter is a consonant, it is replaced by the next letter in the alphabet (+1).
• If the letter is a vowel (A, E, I, O, U), it is replaced by the preceding letter in the alphabet (-1).

Now, let's apply this exact rule to the word CLOSING:
• C (Consonant) → C + 1 = D
• L (Consonant) → L + 1 = M
• O (Vowel) → O - 1 = N
• S (Consonant) → S + 1 = T
• I (Vowel) → I - 1 = H
• N (Consonant) → N + 1 = O
• G (Consonant) → G + 1 = H

Combining these letters gives us DMNTHOH.
