In a doubly reinforced beam subjected to thrust and moment interactions, which condition is true regarding the strain in steel reinforcement?

A) es > ey (tensile strain in steel is greater than yield strain)
B) es < ey (tensile strain in steel is less than yield strain)
C) es = ey (tensile strain in steel is equal to yield strain)
D) es ≥ ey (tensile strain in steel is greater than or equal to yield strain)
