timama [110]

Answer:

The incenter is a point of intersection of all the angle bisectors of a triangle.

The centroid is a point of intersection of all the medians of a triangle.

The incenter, orthocenter, and centroid always lie inside a triangle.

However, a circumcenter does not always lie inside a triangle.

In an acute-angled triangle, the circumcenter may lie inside or outside the triangle.

So,

Option A. is correct
