Correct option is A
Varignon’s Theorem states: "The moment of a
resultant force about a point is equal to the algebraic sum of the moments of all individual forces acting on the system about the same point."
Mathematically,
MR = ∑Mi
where MR is the moment of the resultant force and Mi are the moments of individual forces.
