Which symbol denotes resistance's unit in electrical measurements?

Explanation:
The idea being tested is recognizing the symbol used for the unit of electrical resistance. The unit for resistance is the ohm, and its symbol is the Greek letter Omega (Ω). This ties to the relationship V = IR, where a resistance of one ohm means that applying one volt of potential difference produces one ampere of current. The other symbols correspond to different electrical quantities: volt is for electric potential difference (V), ampere is for current (A), and watt is for power (W). So the symbol for resistance’s unit is Ω.
