Which option lists the symbol for the unit of electrical resistance?

• A. Ohm
• B. Ω
• C. Omega symbol
• D. Resistance unit

Answer: (B)

The symbol for the unit of electrical resistance is the uppercase Greek letter Omega, written as Ω. The ohm is the unit name, and Ω is used in formulas and on instruments to represent resistance, a convention that honors Georg Simon Ohm. The other options describe the unit or its name rather than the actual symbol. In practice you’ll see Ω on meters and in circuit diagrams to denote resistance.
