Voltage = 18 v

Current = 36 amps

Resistance = ?

0.5

I am riled up about those choices. I would say that

none of the choices can be a correct answer.

All four choices are just numbers, without units.

Resistance is not a bare, naked number.

It's a ratio of voltage to current, and in DC circuits,

it typically has units of [ohm].

Resistance = (voltage) / (current)

= (18 v) / (36 A) = 0.5 ohm.
