Statement I : If three forces $\displaystyle \overrightarrow{\mathrm{F}_1}, \overrightarrow{\mathrm{~F}_2}$ and $\displaystyle \overrightarrow{\mathrm{F}_3}$ are represented by three sides of a triangle and $\displaystyle \overrightarrow{F_1}+\overrightarrow{F_2}=-\overrightarrow{F_3}$, then these three forces are concurrent forces and satisfy the condition for equilibrium. Statement II : A triangle made up of three forces $\displaystyle \overrightarrow{\mathrm{F}_1}, \overrightarrow{\mathrm{~F}_2}$ and $\displaystyle \overrightarrow{\mathrm{F}_3}$ as its sides taken in the same order, satisfy the condition for translatory equilibrium. In the light of the above statements, choose the most appropriate answer from the options given below :
