Solution

The correct option is C A small resistance in parallel.
A galvanometer can be converted into an ammeter by connecting a low resistance (called shunt resistance) in parallel to the galvanometer. Parallel resistance being small will draw most of the current and the combination will not effect the original current in the circuit.
