Answer:

$- 32$

Step-by-step explanation:

1) Simplify

$\sqrt{32} \: to \: 4 \sqrt{2}$

$- 8 \sqrt{2} \times \frac{1}{2} \times 4 \sqrt{2}$

2) Use this formula: a/b × c/d = ac/bd.

$- \frac{8 \sqrt{2} \times 1 \times 4 \sqrt{2} }{2}$

3) Simplify.

$- \frac{32 \sqrt{2 \sqrt{2} } }{2}$

$simplify \: 32 \sqrt{2 } \sqrt{2} \: to \: 32 \sqrt{4}$

5) Since 2 × 2 = 4, the square root of 4 is 2.

$- \frac{32 \times 2}{2}$

6) Simplify 32 × 2 to 64.

$- \frac{64}{2}$

7) Simplify 64/2 to 32.

$- 32$

Therefor, the answer is option three -32
