The correct answer is D. 18

is the change in output resulting from employing one more unit of a particular input, for instance, an increase in labour.

From the table above, when the firm had only 1 unit of labour, the output was 10. When it increased its labour to 2, the output increased to 28.

Therefore, marginal product of the second worker = 28 - 10 = 18
