Choose the best alternatives in place of ? out of the four given alternatives (a), (b), (c), (d).
CAT: DDY :: BIG:?

Options

A. CLL
B. CLM
C. CML
D. CEP

Explanation

To solve the analogy CAT: DDY :: BIG: ?, we need to analyze the relationship between the letters in the first pair (CAT and DDY) and then apply the same logic to the second pair (BIG and ?).

### Step 1: Analyze the first pair (CAT: DDY)
- C to D: The letter C is the 3rd letter of the alphabet, and D is the 4th letter. This is a shift of +1.
- A to D: The letter A is the 1st letter, and D is the 4th letter. This is a shift of +3.
- T to Y: The letter T is the 20th letter, and Y is the 25th letter. This is a shift of +5.

So, the shifts for the letters in CAT to DDY are:
- C (+1) → D
- A (+3) → D
- T (+5) → Y

### Step 2: Apply the same shifts to the second pair (BIG)
Now, we will apply the same shifts to the letters in BIG:
- B: The letter B is the 2nd letter of the alphabet. We apply a shift of +1:
- B (+1) → C

- I: The letter I is the 9th letter. We apply a shift of +3:
- I (+3) → L (9 + 3 = 12, which is L)

- G: The letter G is the 7th letter. We apply a shift of +5:
- G (+5) → L (7 + 5 = 12, which is also L)

### Step 3: Combine the results
Putting it all together, we get:
- B → C
- I → L
- G → L

Thus, BIG is coded as CLL.

### Final Answer
The best alternative for BIG in the analogy is **CLL**.
