Answer
Vectors A and B are not equal & vectors B and C are not also equal
Work Step by Step
Two vectors must have the same magnitude & direction to become equal. So they must have identical x & y components.
Vector A & B have different x scalar components of $A_{x}=80\space m\space and\space B_{x}=60\space m. $ So vectors A and B cannot be equal.
Vector B & C have different magnitudes of $B=75\space m\space and\space C=100\space m. $ So vectors B and C cannot be equal.
