Ammeter-It is a device used to measure current and is always connected in series with the circuit.

Voltmeter-It is a device used to measure Potential difference and is always put in parallel with the circuit element whose voltage is to be measured.

The correct experimental circuit diagram to verify the ohm's law is shown in option 1.

Because for option A,

In the circuit diagram, voltmeter V is connected in parallel to the resistor ( R_{eq} ) and ammeter A is connected in series with the resistor ( R_{eq} ).

So Circuit in option (A) can be used to verify the equation
V = IR by varying net resistance of the circuit.
