Answer:
D) Canada since the cost per unit of output will be lower.
Explanation:
A German worker earns $6 per hour with a X productivity, we can assume X = 10 units, so the labor cost in Germany = $6 / 10 units = $0.60 per unit
A Canadian worker earns $10 per hour with a 2X productivity, we can assume X = 10 units, so the labor cost in Canada = $10 / 20 units = $0.50 per unit
Canadian direct labor is 20% more efficient than German labor.
