In this question, it is crucial to notice that each N atom in N2H4 has a lone pair of electrons, while the B atom in BF3 is electron deficient with only 6 electrons.
In part (ii), because there are two atoms of N in N2H4 with lone pairs of electrons, each B atom in BF3 can accept a lone pair of electrons from an N atom via dative bonding to attain a stable octet electronic configuration.
