There are some candies in a bag. Lae Law took one half and 3 more candues. Kyaw Kyaw took one half of the remaining and 9 more. Tun Tun tooke one half of the remaining but 4 less. Finally, 30 candies were left. How many candies did Lae Las take?

A.125
B.54
C.132
D.128.
E.250

Let's denote the total number of candies in the bag as \( x \).

1. **Lae Law's share:**
   - Lae Law took half of the candies and 3 more. This means he took \( \frac{x}{2} + 3 \).
   - The remaining candies after Lae Law's share would be:
     \[
     x - \left(\frac{x}{2} + 3\right) = \frac{x}{2} - 3
     \]

2. **Kyaw Kyaw's share:**
   - Kyaw Kyaw took half of the remaining candies and 9 more. This means he took \( \frac{1}{2} \left(\frac{x}{2} - 3\right) + 9 \).
   - The remaining candies after Kyaw Kyaw's share would be:
     \[
     \frac{x}{2} - 3 - \left[\frac{1}{2} \left(\frac{x}{2} - 3\right) + 9\right]
     \]
     Simplifying this:
     \[
     \frac{1}{2} \left(\frac{x}{2} - 3\right) - 9 = \frac{x}{4} - \frac{3}{2} - 9 = \frac{x}{4} - \frac{21}{2}
     \]

3. **Tun Tun's share:**
   - Tun Tun took half of the remaining candies but 4 less. This means he took \( \frac{1}{2} \left(\frac{x}{4} - \frac{21}{2}\right) - 4 \).
   - The remaining candies after Tun Tun's share would be:
     \[
     \frac{x}{4} - \frac{21}{2} - \left[\frac{1}{2} \left(\frac{x}{4} - \frac{21}{2}\right) - 4\right]
     \]
     Simplifying this:
     \[
     \frac{1}{2} \left(\frac{x}{4} - \frac{21}{2}\right) + 4 = \frac{x}{8} - \frac{21}{4} + 4 = \frac{x}{8} - \frac{5}{4}
     \]

4. **Final condition:**
   - After all these, 30 candies were left, so:
     \[
     \frac{x}{8} - \frac{5}{4} = 30
     \]
     Multiplying the entire equation by 8 to eliminate the fraction:
     \[
     x - 10 = 240
     \]
     Adding 10 to both sides:
     \[
     x = 250
     \]

Now, we calculate how many candies Lae Law took:
   \[
   \text{Lae Law's share} = \frac{250}{2} + 3 = 125 + 3 = 128
   \]

So, the correct answer is **D. 128**.
