Given a mixture with component A boiling at 78°C and component B at 110°C, what distillation method should be used and why?

Fractional distillation, because the boiling point difference is too small.

Fractional distillation, because it provides better yield for any mixture.

Simple distillation, due to a sufficient boiling point difference of 32°C.

Neither method, as the boiling point difference is not sufficient.
