Answer: m< BCA = 2(m<BED)

Step-by-step explanation:

I don't know what ll means in the last one and the other two aren't true. DE_ is not the same size as AC_ let alone 2AC_

Option A: TRUE

By mid-point theorem- If the line segment adjoins midpoints of any of the sides of a triangle, then the line segment is said to be parallel to the remaining side, and it measures to half of the third side.

Here, [tex]DE[/tex] is the line segment joining the mid-points of the two sides of the triangle [tex]ABC[/tex].

[tex]BD=DA[/tex]  i.e., [tex]D[/tex] is the midpoint of [tex]AB[/tex]

[tex]BE=EC[/tex]  i.e., [tex]E[/tex] is the midpoint of [tex]BC[/tex]

So, [tex]DE||AC[/tex] and [tex]DE=\dfrac{AC}{2}[/tex]
