The vectors are said to be equal if they have same magnitude as well as same direction.
In case of C and G,
The direction of both the vectors are same but the magnitude of G is more than C.
Thus, C and G are not equal vectors.
In case of E and D,
Both the vectors have opposite direction to each other and the magnitude of D is more than E.
Thus, E and D are not equal vectors.
In case of B and C,
Both the vectors have same direction but the magnitude of C is more than the magnitude of B.
Thus, B and C are not equal vectors.
In case of A and H,
Both the vectors have same direction and both the vectors cover three boxes, thus, the magnitude of the vectors is same.
Hence, A and H are equal vectors.
