The correct option is (c) Measurement of small currents

The explanation is: Moving Coil Galvanometer is an instrument used for the detection and measurement of current. It is sensitive instrument and can measure current even if it is only a few microamperes. It was invented by Johann Schweigger in the 1800s.
