$(c)$. ammeter.
$(d)$. motor.

Correct Answer: $(a)$. generator

A generator is used for producing electric current. When an armature is rotated in a magnetic field, an electric current is produced. It transforms mechanical energy into electrical energy.

So, option $(a)$: generator is correct.

While the use of a galvanometer is to check the presence of electric current in the circuit and an ammeter is connected to measure the current flowing throw the circuit. And the use of a motor is to convert electrical energy into mechanical energy. When an electric current is passed in an armature placed in a magnetic field, the armature starts rotating.
