To determine the net force on the box, we need more information such as the magnitudes and directions of the forces acting on the box. Without this information, it is not possible to determine the net force on the box.

The correct response would be:
A = Two parents pollen with sperm ovule with egg fertilization
B = New individual organisms are produced *Identical to parent*
C = One parent propagation from plant cutting of leaf, stem or root
