Choose the best alternatives in place of ? out of the four given alternatives (a), (b), (c), (d).
ACE : FHJ :: OQS : ?

Options

A. PRT
B. RTU
C. TVX
D. UWY

Explanation

To solve the analogy problem ACE : FHJ :: OQS : ?, we need to identify the pattern in the first pair (ACE and FHJ) and apply the same pattern to the second pair (OQS and ?).

### Step-by-Step Solution:

1. **Identify the Pattern in the First Pair:**
- The letters in the first group are A, C, and E.
- The corresponding letters in the second group are F, H, and J.
- Let's analyze the positions of these letters in the alphabet:
- A is the 1st letter, C is the 3rd letter, and E is the 5th letter.
- F is the 6th letter, H is the 8th letter, and J is the 10th letter.
- The pattern shows that each letter in the first group is followed by a letter that is 5 positions ahead in the alphabet:
- A (1) + 5 = F (6)
- C (3) + 5 = H (8)
- E (5) + 5 = J (10)

2. **Apply the Same Pattern to the Second Pair:**
- Now, we will apply the same logic to the letters O, Q, and S.
- O is the 15th letter, Q is the 17th letter, and S is the 19th letter.
- We will add 5 to each of these positions:
- O (15) + 5 = T (20)
- Q (17) + 5 = V (22)
- S (19) + 5 = X (24)

3. **Combine the Results:**
- Therefore, the letters corresponding to O, Q, and S after applying the pattern are T, V, and X.
- Thus, the answer to the analogy OQS : ? is TVX.

### Final Answer:
The best alternative in place of the question mark is **TVX**.
