Correct answer: 2:1
Explanation:
In a triangle, the centroid is the point where the three medians intersect.
The centroid divides each median in the ratio: \[ \text{Vertex} : \text{Midpoint of opposite side} = 2:1 \] That is, the centroid is located two-thirds of the way from a vertex along the median.
Hence, the correct ratio is 2:1.
