Area of triangle EBC ?
1)Area of triangle AED = 16
Area of ADC = Area of BDC (common base(BC) and equal height (AD) -(1)

Area(BEC) = Area(BDC) - Area(EDC)
Area(AED) = Area(ADC) - Area(EDC)
Subtracting the left hand and right hand sides
Area(BEC) - Area(AED) = Area(BDC) - Area(EDC) - Area(ADC) + Area(EDC)
Area(BEC) - Area(AED) = Area(BDC) - Area(ADC) = 0 (from (1) above)

So, Area(BEC) - Area(AED) = 0 and Area(BEC) = Area(AED) =16
Sufficient!
(2) The area of �"DEC is 12.
Insufficient!

IMO A
