Answer:

B. 4

Explanation:

Since ,AB is the mid segment of triangle LMN

Then


\Longleftrightarrow AB=(MN)/(2)


\Longleftrightarrow x+8=(5x+4)/(2)


\Longleftrightarrow 2*(x+8)=5x+4


\Longleftrightarrow 2x+16=5x+4


\Longleftrightarrow 16-4=5x-2x


\Longleftrightarrow 3x=12


\Longleftrightarrow x=(12)/(3)=4
