The correct answer is **A. a low resistance shunt is connected in parallel**.
To convert a galvanometer into an ammeter, a low resistance (known as a shunt resistance) is connected in parallel with the galvanometer. This allows most of the current to bypass the galvanometer so it doesn't get damaged by high currents. At the same time, it allows the galvanometer to measure the current through the shunt, which can be used to infer the total current.
To convert a galvanometer into an ammeter, we need to ensure that it can measure larger currents. An ammeter must have very low resistance. Here’s how we achieve this conversion:
Shunt Resistance:
A shunt resistance is connected in parallel to the galvanometer.
The shunt resistance carries the excess current, ensuring the right amount of current flows through the galvanometer.
By adding this shunt, the overall resistance of the circuit becomes very small, allowing the galvanometer to function as an ammeter.
The correct answer is A. a low resistance shunt is connected in parallel
A galvanometer is very sensitive and can only measure small currents. To convert it into an ammeter (which measures larger current):
We connect a low resistance (shunt) in parallel with the galvanometer.
This shunt allows most of the current to bypass the galvanometer.
Only a small safe current passes through the galvanometer, while the rest flows through the shunt.
Why the other options are wrong
B (series shunt) 
wrong: series connection would not bypass current
C (medium resistance in series) increases resistance, not suitable
D (high resistance in parallel) would not divert enough current
E (high resistance in series) reduces current, opposite of ammeter function
N/B
An ammeter must have very low resistance, so it does not reduce the current in a circuit. That’s why a low resistance shunt is connected in parallel.
