Final answer:
Without specific coordinates for the vertices of triangle ABC before and after the proposed transformation, determining the correct vector of translation is not possible.
Step-by-step explanation:
To determine which vector form of translation maps triangle ABC to A'B'C', we would need to look at the coordinates of corresponding vertices and find the differences along the x-axis and y-axis. Since no specific coordinates are given in the question, we cannot determine the correct vector of translation from the options provided.
The vector translation would be a pair of numbers (x, y), representing the movement along the x-axis and the y-axis that each point of triangle ABC undergoes to coincide with triangle A'B'C'. Without additional information or context such as the coordinates of the vertices of the triangles before and after the transformation, choosing an option from A) through D) would be mere speculation.
