The unit of resistance to current flow is the ohm.

Explanation:
The key idea is that resistance is expressed in a specific SI unit: the ohm. By definition, resistance is the ratio of voltage to current (R = V / I), so its unit is volts per ampere, which is the ohm. One ohm means a conductor that drops one volt when one ampere of current flows through it. In practice we also use multiples like kilo-ohms, but the base unit remains the ohm (Ω). So the statement is true because it matches the standard unit used for resistance in circuits.
