A vertical load of $10 \mathrm{kN}$ acts on a hinge located at a distance of $L / 4$ from the roller support $\mathrm{Q}$ of a beam of length $L$ (see figure). The vertical reaction at support $\mathrm{Q}$ is

(A) $0.0 \mathrm{kN}$

(B) $2.5 \mathrm{kN}$

(C) $7.5 \mathrm{kN}$

(D) $10.0 \mathrm{kN}$
