What is the SI unit for distance?

• A. Seconds
• B. Metres
• C. Kelvin
• D. Amphere

Answer: (B)

Distance is a measure of how far something travels, which is a length. In the SI system, length is measured in metres (symbol m). The other options describe different quantities: seconds measure time, Kelvin measures temperature, and the ampere measures electric current. So metres is the unit that fits distance, since it is the standard unit for length. Metres are used to express how far objects move, from everyday distances to precise scientific measurements.
