B Correct answer
Explanation

In any triangle, the centroid divides the median in a 2:1 ratio, with the longer portion between the vertex and the centroid. Given AO = 10 cm (which is 2/3 of median AD), the full median AD = 15 cm. The portion OD = 1/3 of AD = 5 cm. The centroid's property that AO:OD = 2:1 gives us the answer.
