LAST OPTION.

Step-by-step explanation:

For this exercise it is important to remember that, by definition:

1. Any triangle has three medians (which are defined as a segments that join a vertex of the triangle to the midpoint of the opposite side).

2. The medians of  a triangle intersect at a common point. This point is called "Centroid" of the triangle.

3. The Centroid of a triangle is always inside the triangle.

Then, based on the information shown above, you can conclude that the medians of a triangle always intersect in the interior of the triangle.

Therefore, the correct answer is: Inside the triangle.
