Two rectangular under-reinforced concrete beam sections $\mathrm{X}$ and $\mathrm{Y}$ are similar in all aspects except that the longitudinal compression reinforcement in section $\mathrm{Y}$ is $10 \%$ more. Which one of the following is the correct statement?
(A) Section $X$ has less flexural strength and is less ductile than section $Y$
(B) Section $\mathrm{X}$ has less flexural strength but is more ductile than section $\mathrm{Y}$
(C) Sections $\mathrm{X}$ and $\mathrm{Y}$ have equal flexural strength but different ductility
(D) Sections $\mathrm{X}$ and $\mathrm{Y}$ have equal flexural strength and ductility
