Hi! There are 3 statements about the above circle, I think that al the 3 are correct. But the right answer is that only 2 and 3 are correct. Can anyone understand and explain this to me please?

since the circuit is a parallel arrangement of 2 resistances, the current in the circuit will change as the switch is closed. let’s suppose the resistance of the heating element is 1200 ohms, the equivalent resistance will be 400 ohms and the total current will be 0.6 A.

The second and third statements are correct since it is a parallel circuit.
