Answer: (d)

Solution:
A cell, a resistor, a key and an ammeter are arranged in series as shown in the circuit diagrams.
Current is given as: I = V/R
V and R are equal in all the three circuits, so current remains constant.
In series, the order of elements in the circuit does not matter to the amount of current flowing through it.
Therefore, option (d) is correct.
