Best answer
The correct choice is (a) critical moisture content

The best I can explain: The critical moisture content is the average material moisture content at which the drying rate begins to decline. It depends upon the ease of moisture movement through the solid, and hence, upon the pore structure of the solid, sample thickness and drying rate.
