Solution

The correct option is D BF3<BF2NH2<BF2OH<BF4
In BF3, Boron is sp2 hybridised and BF3 is planar molecule. Due to pipi back bonding (back donation) the BF bond acquires some double bond character.
In BF4, Boron in sp3 hybridised and has a tetrahedral shape. It has pure single bonds. Since, double bonds have smaller bond length than single bond and keep in mind the electronegativity factor exhibited by N and O the order of BF bond length follows sequence.
BF3<BF2NH2<BF2OH<BF4
