mihalych1998 [28]

Answer:

The correct option is number 3.  A deficit of appositional bone growth would not be life threatening.

In this kind of bone growth, the diameter of the bone increases rather than the length of the bone. This can lead to deformation of the bone but it is not life-threatening.
