Which One of These Is False When Compared to the Relationship

Which one of these is false when compared to the relationship between marginal and average product?

A) When average product is increasing in labor, marginal product is greater than average product. That is, if $\mathrm { AP } _ { \mathrm { L } }$ increases in $\mathrm { L }$ , then $\mathrm { MP } _ { \mathrm { L } } > \mathrm { AP } _ { \mathrm { L } }$ .
B) When average product is decreasing in labor, marginal product is less than average product. That is, if $\mathrm { AP } _ { \mathrm { L } }$ decreases in $\mathrm { L }$ , then $\mathrm { MP } _ { \mathrm { L } } < \mathrm { AP } _ { \mathrm { L } }$ .
C) The relationship between $\mathrm { MP } _ { \mathrm { L } }$ and $\mathrm { AP } _ { \mathrm { L } }$ is not the same as the relationship between the marginal of anything and the average of anything.
D) When average product neither increases nor decreases in labor because we are at a point at which $\mathrm { AP } _ { \mathrm { L } }$ is at a maximum, then marginal product is equal to average product.
