Prestressed concrete is often used in modern construction because:
a. its unique strength allows predetermined engineering stresses to be placed in members to counteract stresses that occur when the unit is subjected to service loads
b. it is "scored" in certain areas, which allows it to break apart predictably when a building explodes
c. it doesn't normally have end anchors, which makes it easier to attach to adjacent members
d. both b and c
