The marginal product of labor refers to the additional output produced as a result of adding one more unit of labor, which is captured by all the given options: it is indeed the change in output from a one-unit change in labor (A), can be represented by the slope of the total product curve at any given point (B), and can vary in its impact on output, being positive at some levels of input when additional labor increases output, and negative at others when it leads to decreases in output due to factors like overcrowding or inefficiency (C).
