D. `b b aaa`

Answer

To fill in the blanks in the sequence `a_ a a b b _ _ ab _ b _`, we need to analyze the pattern in the sequence.

### Step-by-Step Solution:

1. **Identify the Given Sequence**:
The sequence is: `a _ a a b b _ _ ab _ b _`.

2. **Analyze the Pattern**:
Let's break down the sequence:
- The first part is `a _ a a b b`.
- The second part is `ab _ b _`.

3. **Fill in the First Blank**:
Looking at the sequence, we notice that after the first `a`, we have another `a` and then two `b`s. To maintain a pattern, we can fill the first blank with `b`.
- So, it becomes: `a b a a b b _ _ ab _ b _`.

4. **Fill in the Second Blank**:
Now, let's look at the next part: `a b b _ _ ab _ b _`.
We can fill the second blank with `a` to maintain the pattern of alternating `a` and `b`.
- So, it becomes: `a b a a b b a _ ab _ b _`.

5. **Fill in the Third Blank**:
Next, we look at `ab _ b _`. The blank can be filled with `b` to continue the pattern.
- So, it becomes: `a b a a b b a b ab _ b _`.

6. **Fill in the Fourth Blank**:
Finally, we look at the last blank. The pattern suggests that we can fill this with `a`.
- So, the final sequence is: `a b a a b b a b ab a b`.

### Final Sequence:
The completed sequence is: `a b a a b b a b ab a b`.
