`- - G - A - GT - M - T`

Options

A. AMTMAG
B. MTAGAM
C. GAMATG
D. TMTAGM

Explanation

To solve the series completion question `- - G - A - GT - M - T`, we need to identify the pattern in the sequence and fill in the blanks accordingly.

### Step-by-Step Solution:

1. **Identify the Structure of the Series:**
The series is composed of alternating letters and dashes:
`- - G - A - GT - M - T`
We can see that there are letters in certain positions and dashes in others.

2. **Group the Letters:**
Let's break down the letters we have:
- The letters present are: G, A, GT, M, T.
- The dashes represent missing letters.

3. **Look for Patterns:**
We can observe that the letters seem to follow a certain order. If we analyze the letters:
- The first letter in the sequence is G.
- The second letter is A.
- The third letter is GT.
- The fourth letter is M.
- The fifth letter is T.

4. **Fill in the Blanks:**
To find a consistent pattern, we can hypothesize that the letters might follow a specific order. If we assume a repeating sequence, we can try to fill in the dashes:
- The first dash could be A (to follow G).
- The second dash could be M (to follow A).
- The third dash could be T (to follow GT).
- The fourth dash could be G (to follow M).

Therefore, filling in the dashes gives us:
`A A G M A GT M T`

5. **Check for Consistency:**
Now we can check if this sequence makes sense:
- The sequence can be seen as alternating letters: A, M, G, T.
- This suggests a repeating pattern of AMGT.

6. **Final Answer:**
The complete sequence would be `A A G M A GT M T`, which corresponds to option A.
