abb - baa - a - bab - ab

Options

A. abba
B. abab
C. c cac
D. aabb

Explanation

To solve the given series: abb - baa - a - bab - ab, we need to identify the pattern in the sequence of letters.

### Step-by-Step Solution:

1. **Identify the Series**: The series given is: abb, baa, a, bab, ab.

2. **Analyze the Patterns**:
- The first term is **abb**.
- The second term is **baa**.
- The third term is a single letter **a**.
- The fourth term is **bab**.
- The fifth term is **ab**.

3. **Look for Repetitions**:
- Notice that the first two terms (abb and baa) both contain the letters a and b.
- The third term is simply **a**, which might indicate a transition or a reset in the pattern.
- The fourth term **bab** contains both letters again.
- The last term **ab** is a combination of both letters.

4. **Formulate the Next Term**:
- The terms seem to alternate between combinations of **a** and **b**.
- After analyzing the series, it appears that the terms are constructed by rearranging the letters a and b.
- The pattern seems to be:
- Start with a combination of letters, then reduce or rearrange them.
- After **ab**, we may expect a return to a previous combination.

5. **Predict the Missing Term**:
- Following the pattern, after **ab**, we can expect a term that includes both letters again.
- The previous terms suggest that we might return to **abb** or **baa**.

6. **Final Conclusion**:
- Given the previous terms, the most logical continuation of the series would be **abb**.

### Final Answer:
The missing term in the series is **abb**.
