Hello, could any expert help me with this materials resistance exercise, thank you.

material resistance activity $3$:

The rigid beam is supported by a pin at A and by the cables at $BD$ and $CE.$ If the distributed load causes end Cto move $12$ mm downward; and if the cables have a diameter of $4$ mm and E$=200$GPa and the pin has a diameter of $8$ mm $.$ The stresses in the cables and the shear in the pin are:

Choosethe correct option and carry out the entire procedure:

a$.\{CE\}=0\mathrm{.}53$GPa,$\{BD\}=1$GPa,$\{A\}=0\mathrm{.}396$GPa

b$.\{CE\}=1$GPa,$\{BD\}=0\mathrm{.}53$GPa,$\{A\}=0\mathrm{.}396$GPa

c$.\{CE\}=1\mathrm{.}2$GPa,$\{BD\}=0\mathrm{.}64$GPa,$\{A\}=0\mathrm{.}267$GPa

d$.\{CE\}=0\mathrm{.}64$GPa,$\{BD\}=1\mathrm{.}2$GPa,$\{A\}=0\mathrm{.}267$GPa
