Propped Cantilever Beam AB Has Moment $M_{\mathrm{I}}$ Applied at Joint B $M_{2}$

Propped cantilever beam AB has moment $M_{\mathrm{I}}$ applied at joint B. Framework ABC has moment $M_{2}$ applied at C. Both structures have con-
Stant flexural rigidity EI. If the ratio of the applied moments $M_{1} / M_{2}=3 / 2$ the ratio of the reactive moments $M_{A 1} / M_{A 2}$ at clamped support A is
Approximately: (A) 1
(B) $3 / 2$
(C) 2
(D) $5 / 2$
