In which stage of production, the total product increases first at increasing rate and then increases at decreasing rate?

Correct option is A

1. Total Product (TP) initially increases at an increasing rate due to better utilization of resources and efficiency.

2. Marginal Product (MP) also increases, indicating that each additional unit of input contributes more to the total output.

3. However, after a certain point, TP continues to increase but at a decreasing rate, as the effect of additional inputs starts to diminish.
