Answer: A. small resistance in parallel with it

Answer: (a) small resistance in parallel with it

A low resistance (shunt) \(S = \dfrac{I_g G}{I - I_g}\) is connected in parallel with the galvanometer so that most of the current bypasses the coil and the ammeter as a whole has a very low resistance. (A large series resistance converts it into a voltmeter.)
