`- - G - C - GK - PG -`

Options

A. KCPCPK
B. CPKPCK
C. PKCPKP
D. CPPKCP

Explanation

To solve the series `- - G - C - GK - PG -`, we need to identify the pattern in the sequence and fill in the blanks accordingly.

### Step-by-Step Solution:

1. **Identify the given elements**: The series has some letters filled in and some blanks. The letters present are G, C, GK, and PG.

2. **Group the elements**: We can divide the series into groups of letters. The series can be observed in segments:
- First segment: `- - G -`
- Second segment: `C - GK -`
- Third segment: `PG -`

3. **Analyze the segments**:
- In the first segment, we have two blanks before G and one blank after G.
- In the second segment, we have C followed by a blank and then GK.
- In the third segment, we have PG followed by a blank.

4. **Look for a pattern**:
- If we observe the letters, we can try to create a sequence.
- The letters G, C, GK, and PG can be arranged or repeated in a certain order.

5. **Establish a sequence**:
- Let's assume a repeating pattern of letters.
- We can try to fill in the blanks with letters that would create a consistent pattern.
- Based on the letters we have, we can try to fill in the blanks with C, P, G, and K in a repeating manner.

6. **Fill in the blanks**:
- If we fill the first blank with C, the second blank with P, the third blank with K, the fourth blank with C, and the fifth blank with K, we can create a pattern.
- Thus, we can fill the series as:
- C P G C K G K P G

7. **Check for consistency**:
- After filling in the blanks, we can check if the pattern holds.
- The sequence maintains a consistent order and repeats the letters in a logical manner.

8. **Select the correct option**:
- Based on the filled sequence, we can compare it with the given options.
- The option that matches our filled sequence is option B.

### Final Answer:
The answer is **option B**.
