To solve this problem we will simply use the lens equation.
1/d+1/i=1/f

Where d is the object distance, i is the image distance and f is the focal point distance.
We can solve this equation for i:
$1/d+1/i=1/f\\
1/i=(1/f-1/d )\ \cdot \frac{df}{df}\\
1/i=\frac{d-f}{fd}\\
i=\frac{fd}{d-f}$
Now we plug in the numbers:
$i=\frac{fd}{d-f}\\
i=\frac{0.5\cdot 1}{1-0.5}\\
i=1m$
The answer is A.
