The correct answer is given below

Explanation:

B before the reaction boron is sp2 hybridized and after the reaction boron is it is sp3 hybridized.

Before the reaction boron is joined to 3 fluorine atoms by 3 covalent bonds between them one is s and rest of the 2 are p. That"s why before the reaction boron is sp2 hybridized.

Whereas after the reaction boron is joined to 3 fluorine atoms by 3 covalent bonds and one nitrogen atom by one co ordinate bond. That"s why after reaction boron is sp3 hybridized.

B before the reaction nitrogen is sp3 hybridized and after the reaction it is sp3 hybridized.

Before the reaction Nitrogen is joined to 3 hydrogen atoms by 3 covalent bonds and contain one lone pair of electron. That"s why before the reaction Nitrogen atom is sp3 hybridized.

whereas after the reaction Nitrogen is joined to 3 hydrogen atoms by 3 covalent bonds and with one boron atom by a co ordinate bond. That"s why after reaction Nitrogen atom is sp3 hybridized.
