Solution

The correct option is D low resistance in parallel
To convert a moving coil galvanometer into ammeter low resistance is be connected in parallel. Since, in parallel combination of resistances, the equivalent resistance is less than the lowest resistance in combination. Also, ammeter must have very low resistance in order to read the exact current in the circuit.
