In this type of question , two groups of letters related to each other in same way are given . It is requird to find out this relationship and then choose either a letter-group of a pair consisting of similarly related letter-groups out of the given four alternatives.
A : Z :: B :?

Options

A. C
B. X
C. Y
D. Z

Explanation

To solve the analogy question A : Z :: B : ?, we need to determine the relationship between the first pair of letters (A and Z) and then apply that same relationship to the second pair (B and ?).

### Step-by-Step Solution:

1. **Identify the Relationship Between A and Z:**
- The letter A is the 1st letter of the English alphabet.
- The letter Z is the 26th letter of the English alphabet.
- The relationship can be seen as A being the first letter and Z being the last letter. They are opposites in terms of their position in the alphabet.

2. **Determine the Position of B:**
- The letter B is the 2nd letter of the English alphabet.

3. **Find the Opposite of B:**
- To find the opposite of B, we need to determine which letter corresponds to the same position from the end of the alphabet.
- Since B is the 2nd letter, its opposite would be the 25th letter (26 - 2 + 1 = 25).
- The 25th letter of the alphabet is Y.

4. **Conclusion:**
- Therefore, if A is related to Z, then B is related to Y.
- The answer to the analogy A : Z :: B : ? is Y.

### Final Answer:
B : Y
