The problem in the image asks to evaluate the following expression:

\[
\sqrt{1 - \frac{1}{4}} \cdot \left( \sqrt{16 + \frac{1}{3}} - \sqrt{9 - \frac{2}{3}} \right) = ?
\]

Let’s solve this step by step:

### Step 1: Simplify the first square root:
\[
\sqrt{1 - \frac{1}{4}} = \sqrt{\frac{4}{4} - \frac{1}{4}} = \sqrt{\frac{3}{4}} = \frac{\sqrt{3}}{2}
\]

### Step 2: Simplify the second square root:
\[
\sqrt{16 + \frac{1}{3}} = \sqrt{\frac{48}{3} + \frac{1}{3}} = \sqrt{\frac{49}{3}} = \frac{\sqrt{49}}{\sqrt{3}} = \frac{7}{\sqrt{3}} = \frac{7\sqrt{3}}{3}
\]

### Step 3: Simplify the third square root:
\[
\sqrt{9 - \frac{2}{3}} = \sqrt{\frac{27}{3} - \frac{2}{3}} = \sqrt{\frac{25}{3}} = \frac{\sqrt{25}}{\sqrt{3}} = \frac{5}{\sqrt{3}} = \frac{5\sqrt{3}}{3}
\]

### Step 4: Subtract the square roots from Step 2 and Step 3:
\[
\frac{7\sqrt{3}}{3} - \frac{5\sqrt{3}}{3} = \frac{(7 - 5)\sqrt{3}}{3} = \frac{2\sqrt{3}}{3}
\]

### Step 5: Multiply the result by the first term:
\[
\frac{\sqrt{3}}{2} \cdot \frac{2\sqrt{3}}{3} = \frac{\sqrt{3} \cdot 2\sqrt{3}}{2 \cdot 3} = \frac{2 \cdot 3}{6} = 1
\]

Thus, the result of the expression is **1**.

The correct answer is **C) 1**.
