Option 1 -> At maximum MP, the curves do not necessarily intersect; MP reaches its peak before AP.
Option 2 -> The intersection does not occur at the minimum point of MP curve.
Option 3 -> The intersection occurs at the maximum point of AP, not at its minimum.
Option 4 -> When MP > AP, the AP rises; when MP < AP, the AP falls. Therefore, MP must equal AP at AP's maximum point. Since MP reaches its maximum before AP does, MP is declining when it intersects AP, cutting it from above.
Hence, Option 4: Marginal product curve cuts the average product curve from above at the maximum point of average product curve. -> This follows the fundamental relationship: when MP > AP, AP is rising; when MP < AP, AP is falling. Thus, MP = AP at the maximum of AP. Since MP peaks before AP, MP is already declining when intersection occurs, cutting AP from above at AP's maximum point. This is a key principle in production theory. -> correct
