Solution

The correct option is D 18ar(ΔABC)
In ABC, it is given that D is the midpoint of BC, E is the midpoint of BD and O is the midpoint of AE.
Then BE=14BC OR OE=12AE
WE know thet area of triangle =12h.b
Area of triangle ABC=12BC(AE)
Area of triangle BOE=12BE(OE)
Then area of triangleBOE=18area of triangleABC
