Solution

The correct option is C 6 cm
A base is perpendicular to altitude and side of the triangle.

The height of the triangle is the length of the altitude drawn to its base.

We have 3 altitudes in a triangle. Here the base of the triangle is mentioned as BC so height is the length of altitude drawn to BC. Hence, it is 6 cm.
