Statement-$I$: If three forces $\vec{F}_{1}, \vec{F}_{2}$ and $\vec{F}_{3}$ are represented by three sides of a triangle and $\vec{F}_{1} + \vec{F}_{2} = -\vec{F}_{3}$,then these three forces are concurrent forces and satisfy the condition for equilibrium.
Statement-$II$: $A$ triangle made up of three forces $\vec{F}_{1}, \vec{F}_{2}$ and $\vec{F}_{3}$ 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:

• A
  Statement-$I$ is false but Statement-$II$ is true.
• B
  Statement-$I$ is true but Statement-$II$ is false.
• C
  Both Statement-$I$ and Statement-$II$ are false.
• D
  Both Statement-$I$ and Statement-$II$ are true.
