Solution

The correct option is D
Statement 1 and Statement 4 are correct

Nonmetals are generally poor conductors of electricity, hence Statement 1 is true. Filament of a bulb is a thin wire, so Statement 2 is false. For a circuit to work there has to be potential difference between two ends, so an electric cell is needed. Hence Statement 3 is false. Current flows from positive to negative terminal, so Statement 4 is also true.
