Which identifies a machine that converts mechanical energy into electrical energy?

a. motor

b. electromagnet

c. generator

d. turbine

The answer is the option c. generator. Generator is a machine that converts mechanical energy into electricity. The way it is made is because the mechanical movement may be transformed in rotation of magnets placed inside a coiled wire, and this induces the movement of electrons through the coiled wire. As you know electricity is the flow of electrons.
