Select the correct statements here
${\mathrm{H}}_3\mathrm{N}:+\mathrm{B}{\mathrm{F}}_3\to {\mathrm{H}}_3\mathrm{N}\to \mathrm{B}{\mathrm{F}}_3$

• A

  Here $\mathrm{N}{\mathrm{H}}_3$ is Lewis base while $\mathrm{B}{\mathrm{F}}_3$ is Lewis acid
• B

  Hybridisation of $\mathrm{B}{\mathrm{F}}_3$ becomes $\mathrm{s}{\mathrm{p}}^3$
• C

  Shape of $\mathrm{B}{\mathrm{F}}_3$ remains trigonal
• Correct answer
  D

  Both A and B

Hence, the correct answer is option: 'D'.
