Consider the plane truss with load $\mathrm{P}$ as shown in the figure. Let the horizontal and vertical reactions at the joint $\mathrm{B}$ be $\mathrm{H}_{\mathrm{B}}$ and $\mathrm{V}_{\mathrm{B}}$, respectively and $\mathrm{V}_{\mathrm{C}}$ be the vertical reaction at the joint $\mathrm{C}$.
Which one of the following sets gives the correct values of $\mathrm{V}_{\mathrm{B}}, \mathrm{H}_{\mathrm{B}}$ and $\mathrm{V}_{\mathrm{C}}$ ?
