Answer:
Segment AD is 3, and segment AE is 2.
Step-by-step explanation:
In a triangle, the line joining the mid points of two sides is parallel and half of the third sides of the triangle.
Here, ABC is a triangle,
In which,
AB = 6,
AC = 4,
D∈ AB and E∈AC
Let DE ║BC,
And, 
In triangles ADE and ABC,
( Alternative interior angle theorem )

By AA similarity postulate,

∵ Corresponding sides of similar triangle are in same proportion,





Hence, the correct option would be,
Segment AD is 3, and segment AE is 2.
