To convert an AC generator into DC generator

  1. split-ring type commutator must be used
  2. slip rings and brushes must be used
  3. a stronger magnetic field has to be used
  4. a rectangular wire loop has to be used

Answer

AC generator has slip rings while the DC generator has a split ring type commutator. To convert an AC generator into DC generator the split ring type commutator with which unidirectional current is obtained.

The correct option is A.
